We had a wonderful time in Florence and enjoyed our stay at Dimitri's place. Location was good - just outside of all the major sites and Florence is small enough so everything is very accessible by foot.
The apartment was good - very clean. Bathroom size is great. The apartment is a loft style so you have to climb a small staircase to get to the bedroom. The ceiling height for the bedroom is a bit shallow but not too bad as we mostly stayed downstairs anyway. Dimitri was very kind.
