The apartment is very well maintained and very clean. In the surroundings there are tons of very nice pubs and bistros and you want to stay longer than expected to try them all!
In a few minutes you can walk to the Santa Maria Novella station and, if you come by car as I did, there are two parking lots in the surrounding streets about 100 meters from the apartment (call the parking lot before going because both the house and the parking lots are in the limited traffic zone and they will explain you how to enter without risking fines!).
Check-in is very easy and the host is very precise and quick to respond.
