Carlotta is a great host with two lovely dogs. We had difficulty finding the bus to her place, and she helped us on the phone. She also gave us information about places to go in Florence.
The apartment is smaller than we imagined, but you can't beat the price and its perfect location. We visited most of the attractions on foot. There were lots of shops, restaurants and bars nearby, but in general the apartment is quiet enough. The only thing is there was only one fan in the house and it was a bit too hot during our stay. A pleasant stay I'd say, and I reccomend this apartment to all of you :)
