My girlfriend and I spent three nights in Rolando's flat close to the Porto Vecchio.
The flat is located in a top area and all the important sights like the Uffizi, Palazzio Vecchio, il Duomo, Palazzo Pitti or the beautiful viewpoint Piazza Michelangelo are very close and you can easily walk there by foot.
I stayed in contact with the very friendly owner Rolando, who answered every question within three minutes. When we arrived at seven o'clock in the morning he let us enter the flat without any problems and showed us everything. The flat was very clean and confortable... So all in all we had a wonderfull weekend in Firenze.
Mille Grazie Rolando
