The place is great! Location is perfect, very near from the station and near of the main points of the city.
The apartment was very clean and everything was fine. The host always answered my questions very quickly.
Just one point should be considered if you carry large luggage: the apartment is located in the 3th floor, and there is no lift inside the building. Besides that, one room is located in the second floor of the apartment and the stairs are tiny to carry a luggage to there. In our experience, we decided to leave the luggage in the living room in the 1st floor instead of carrying it upstairs.
In general I recommend the place to stay a few days in Florence. You will enjoy it.
