This place is beautiful. On the South side of the river, it is a short walk to get to the tourist sights of Florence. This is not a negative, however, as it is close to a number of less touristic areas with outstanding food, wine bars etc. The location is perfect in my opinion. Very clean accomodation, too.
Jonny himself is a great host, check in was easy, and whilst we didn't see much of him beyond that I know he was just at the other end of the phone.
If we are able to squeeze in another trip to Florence, we'll be returning to Jonny's studio without hesitation.
