I spent 4 wonderful days in Florence. The Claudio's flat is perfectly situated: in 10 min from the railway station, in 5 min from the Duomo's place, and there are a lot of nice cafes just around where you can take a breakfast.
The room is cosy, clean and confortable. It is spacious and furnished. There is also a GREAT private bathroom! (Special thanks for it.)
I felt very good at the Claudio's flat, and he is very nice also!

Thank you Claudio! ;-)
