We only had 24 hours in Florence, just a taste of a city that we really hope to visit again! Costanza's place was more than we needed really. It is very big and spacious, apart from the tiny bathroom, which is as the pictures show and was totally fine for us.
The location is good for a more local feel, in the evening we were recommended a square to eat in by a tour guide, which was less than 10 mins walk away. For most of the major attractions it is a 15-20 min walk over the river.
Thanks for a great stay Costanza!
