The apartment with its lovely garden really helped us feel we were in Florence. It was comfortable, with 3 separate bedrooms, a washer and heated drying rack winter guests might appreciate. Sonia was wonderful - she met us for check in at 9 when we found we were running late, let us keep our luggage there a few extra hours, and arranged a taxi for us. She also explained public transit but as there were 4 of us, the 15 euro taxi from the station and 27 euro taxi to the airport wasn't unreasonable.
The restaurant around the corner from the apartment is lively and crowded in the evening (last order is 10:30) with a real neighborhood feel. The main areas of Florence can be reached in about 20 minutes.
