My wife and I stayed at Lorenzo's apartment in Florence during our honeymoon. The apartment's location is amazing, it's just south of the river, in a historic area of Florence, a little bit away from the tourist areas. The apartment was immaculate, with plenty of space. A few really nice touches included a welcome note and a bottle of wine when we checked in. One other thing that was extremely useful is the mobile wifi hotspot Lorenzo let us barrow!

The only negative thing i can think of is that it seems that the walls are a bit thin, but neighbors are very respectful and it's fairly quiet regardless.

This has got to be one of the best airbnb's we stayed at, if you're looking for a place to stay in florence, this is it!
