We had a very nice stay at Firenze. It is a beautiful city and easily walkable from the appartment. The appartment was perfect for 2 people. The apparment was cool (in the sense of not hot) and very clean.
However I would like to mention that the appartment nor the office where we had to collect our keys was accesible by car.
Also the warm water was not directly working, however we told the host (Keys of Italy) and they fixed it first thing in the morning, so quick response is a big plus.
