Casa Bixio is a comfortable and nice flat, we found everthing we need, e.g. adapters, cooking equipment and hairdryer. Also the apartment was clean, there was really nothing to complain about.
Pietro answered quickly on our request and gave us precise directions to get to the flat. The apartment is located outside of the city centre, it took us about 25 min to walk to the Duomo, but there was also a bus stopping close to Casa Bixio that brought us close to most of Florence's sights.
We really enjoyed our stay and we would definitly recommend it.
