my address: well ... i will not tell you.
... at least not now. (unless you already know it)
Most of the days, at the time I ask guests to arrive, I could be in one of three other places; these places are all within three minutes from my home, so in case I need to go there I may call the arriving guest and tell them either to meet in that place, or just when arriving at a place 500 meter from my home call me so I can go back home just in time.
To accomplish this of course the guest must have a working phone.
Unfortunately sometimes I have had guests that did something that annoyed me and the other guests: that is, they deliberately gave me a phone number of some other people, so when I called them to ask why they were late replied a person that could speak only chinese, some 90 yr old ladies, and so on (including in one case someone living 8 timezones east), or gave me a phone that effectively was their one, but had not active roaming on the day they arrive in Firenze or was out of credit, leaving me and other guests unable to know if wait or start cooking, or forcing me to go back home to wait for them at arranged time, leaving another job, and then waiting sometimes for more than 40 minutes.
In october 2014 this happened two days in a row, so I came to a decisone to give my address in two parts.
One, the most significant is described here, until point "X", at junction of via del Guarlone and Via della Loggetta: that one is a point very close to my home; the second part, the real address, that is less than 200 meters from that place, will be told you by phone, i will call you at random time some hours before arrival to the number from whom you will have sent me the confirmation SMS [my phone number is in the signature of all email messages] or called me. Please no excuses telling that someone stole your phone the day before. A phone with a sim can be get for less than 25 EUR !
So for now print the map (landscape and complete) and these istruction, and answer my call when I will give you the last indication.
Please check anyway to have my address when you are arriving ... sometime happen that for some reason is lost, so feel free to send me a sms asking to resend it ... but remember that using GPS batterie get depleted quickly, so make an hardcopy of the map.
Also I have to tell you that after 1900 the day of arrival I do not promise quick reply to email messages and SMS so ask only with voice calls, and when arriving ring directly the doorbell.

EXTREMELY IMPORTANT:
I have had many people that arrived late, up to 2 hours, since they asked people the way to come here, and due to miscommunication or ignorance of the people asked, get rerouted throu much longer itineraries
If you are late due a wrong information it will be due to YOUR fault.
Same if you do not answer my phone call in case I am going to suggest an alternate route in case I got aware of last minute diversion, or traffic problem. Feel free to call me (voice) if you are even just a bit lost.
From the center:
Arrive to the river and follow it upstream on the right bank (that is the northern one) going toward east until you arrive to via De Nicola. You can easily spot it since it is in a place where the road part a few meters from the river, there is a theater on the right [ask for Tuscanyhall] and more evident a roundabout [with a fountain in the middle].
There turn left into via della Casaccia, at next roundabout continue straight into the underpass under the railway, and at next very oblongated roundabout get the second right, via del Guarlone, you will arrive at point X; the last 200 meter will be given when you send the confirmation SMS.
From Pontassieve (SS67)
Arriving at city border, after il Girone, just before the railway overpass there is on the right a ramp passing under the railway from Pontassieve, get it and turn left along the railway, the road become very, very narrow, follow it and continue for about 900 m turning on the second road on the right, via della Loggetta (green line)(it is against the flow, so be careful, but you save almost 2km)
From Bagno a Ripoli/Candeli
go toward "Nave a Rovezzano" then get the lower level of the "ponte di Varlungo" stay on the pedestrian lane, since after the river it goes lower and you can access the road along the river, go there toward west (downstream) until you arrive to via de André follow it until the roundabout with the fountain, then go ahead in via della Casaccia and follow in the same way as described for coming from the center.
From via Chiantigiana (SR 222)
follow via Chiantigiana until Badia a Ripoli, the go ahead into via Cimitero del Pino, then left on viale Europa, right via Olanda, then right via Austria and on lower level of Varlungo bridge, as described above
From Faenza/Borgo San Lorenzo (SR302)
when you arrive at Vetta le Croci turn left on SP54 direction Fièsole until km 1,200, Baccano, where you turn left into SP55, following signs to Montebeni-Vincigliata. Keep right on the next two junction always following signs to Vincigliata until at the end of the road you arrive at Ponte a Mensola, where you turn right into via d'Annunzio and after about 200 m turn on the third left, via del Gignoro, at first junction turn right, passing between the football fields turn right at the next one, until you arrive at big roundabout in piazza San Bartolomeo, where you turn toward left in the roundabout, following via del Gignoro; at the third roundabout turn left into via Pasquali, between the houses, keep going left and turn left into via del Guarlone. note that if you want get a long downhill you could follow indications to Montebeni and there to Compiobbi (then SS67)
From Vaglia (SR65)
When you arrive at Pratolino, on top of the pass, you have two options: one more scenic to go left to Vetta le Croci and follow same indications as if coming from from SR302, else go straight down until il Cionfo where you may turn left into via Salviati and go further down until the crossing with via Faentina, then go right until piazza delle Cure, then viale dei Mille and at the 4th light right into via Marconi, then left via del Pratellino and right via del Campo d'Arrigo. at the end left and immediately right in via Tito Speri, continue into via Andrea del Sarto, and right via del Mezzetta until the end, where you will do three quarters of the roundabout to continue in via del Guarlone.
From Pisa (SS67)
Easier way (aven if a bit more hilly): follow via Pisana until piazza Pier Vettori there turn right via Aleardi, viale Tasso to Porta Romana, then via Machiavelli (follow signs to piazzale Michelangelo), viale galilei (bicycle lane on muntain side), viale michelangelo, cross river and follow indications as from the center.

in alternative at piazza Pier Vettori do 3/4 around and get via del ponte sospeso, cross the river, and follow viale Rosselli-viale Strozzi-viale Lavagnini-viale Matteotti-viale Gramsci-viale Giovine italia and you are along the river again (there is a shortcut too, but due some roadworks from april 2021 until october 2024 there are a couple of detours and the risk to get lost is too big for the small advantage in time).
From Siena (SR2)
Until "due strade" follow SR2, then turn right into via del gelsomino, ahead in viale Torricelli, then viale Galilei, viale Michelangelo, ponte san Niccolò and right along river upstream
from Prato-Calenzano-Sesto:
arrive from via sestese, via Giuliani, via corridoni, via del romito. At the roundabout at end of via del Romito turn left on right bank of Mugnone until Ponterosso, then follow signs to Fiesole until you cross the bridge on the railway and from there (piazza delle cure) follow the indications as from Vaglia (SR65)
from other directions
go toward the river, then as described from the city center
maybe If you use a navigator in the city I recommend to set if for "Cars", so it will avoid pedestrian areas wher bicycle even if allowed cannot go more than 7-8 km/h.
