Our stay at Guido's apartment was perfect.
The location could not be better. In front of Santa Croce Church, but also 3 minutes away from Palazzo Vecchio and Uffici Gallery. Location is perfect because is close to all the main attractions, but also because the area is peaceful and quiet.
The apartment was bigger than expected, clean and beautiful. The air conditioner worked good, and also the wifi.
It is in the 4th floor, but if you planning to go to Firenze, you should be ready to go upstairs...
I would definitely be back to this apartment. Guido also booked a taxi for us, thank you very much!
