The aparment is very nice and comfortable and it is located in the quiet part of town. It is fully equiped. You can get to the center on foot in approx. 20 minutes. It is very well connected with the main train station (Santa Maria Novela) as the local bus (1A) we took outside the train station left us right in front of Roberto's building.
We loved staying there and if we were to come back to Florence I'm sure we would stay at Roberto's!
