We had a great stay at Claudio's place. His friend met up with us to give us the keys to the place and helped us carry the suitcases upstairs. Thank you again for that!
The flat is really nice - lots of stairs to walk up there but it's worth it - with a nice view over the roofs. His flat is in walking distance to all the sightseeing places.
We really enjoyed our time in Florence and we highly recommend staying at Claudio's place.
