Nice little apartment and very handy for the train station as it's only a 10-15 minute walk. Same for the centre of Florence, an easy walk from the apartment.
A lot of stairs to get up to the apartment so just keep that in mind if you have heavy luggage. The apartment itself is very chic and has great kitchen facilities, although a bit of an ant problem.
The shower is extremely narrow so it's a bit awkward. We thought the extra charge to use more towels was a bit hostile.
Overall a nice apartment in a nice location.
