I stayed at Chiara and Nicola's place for 11 days. Nicola checked me in and he's friendly and help me carry my luggage up to the 2nd (3rd for American) floor apartment. He showed me where we at and the basic surroundings on the map. During my stay, Chiara also checked in with me to see how I'm doing. Chiara and Nicola's place is at a great location and it has everything you could need, hair dryer, converters and umbrella which saved me from the one raining day in Firenze during my stay. The location is really the best, make a right, you can head to tourist zone, make a left to santa Croce, is where locals and a lot of architecture students hangout. I would definitely come stay again if I'm in Florence again.
Grazie!
