We had a nice stay at this appartment. Well situated, not far from the station, and not far from the city center. You can do everything by foot. And the bus to Fiesole passes in front of the door.
The appartment is very well furnished, good bed, enough place, good kitchen, good bathroom.
Michaelis was welcoming is very well with all the tips we needed.
It's just a little noisy in the street. But it's probably not easy to find a quiet place in Florence...
