The location of the house is really great. It was close to the train staion & Cathedral of Santa Maria del Fiore. But it could be noisy in the bedroom because it is right next to the main street. If you are a light sleeper, I suggest to sleep in the living room.
The house was located on the 6th floor (maybe 5th floor...i can't remember) without the elevator. Thanks to Andrea for helping my family to move the luggage when we checked-in.
Also, because it is almost top floor of the building, it is really hot during the daytime.
You need to use A/C all the time.
Although many people complained about the wi-fi, i had no problem with it. I could watch YouTube without any buffering.
Overall, it was great stay then I expected. The price was cheap when you think the location. I would stay here again if i visit Florence.
