We stayed at Matilde's during May's bank holiday weekend. It is a nicely decorated flat in a residential area just outside the city centre, comfortable enough to host four of us in the main bedroom and living room with sofa bed. The city centre can be reach in 20min walking. A new tramway is currently under construction which will provide quicker public transport links. I definitely recommend this place if you want to avoid the city centre buzz and look for a reasonably priced accommodation in Florence.
