We really loved the apartment - it has everything you need, is located in a great area (not very touristy but in walking distance to the main station, Ponte Vecchio etc.) with many nice restaurants and is really spacious and clean! The only downside for big people might be the tiny bathroom, but it is freshly renovated and very clean.
Contact with Andrea was also very good, we got a lot of information on how to get there and so on, everything was perfectly organized and really easy for us!
