Mauro is a perfect host and so is his appartment in Florence! We had a wonderfull time there. Even though the appartment is not in the city centre it is located in a really convenient place, 5-7min walk from the station (which was very important for us because we travelled every day to different Toscana towns by trains).
Thanks to Mauro's usefull tips (there's a list of must-see/must-go places in the appartment) and to the books about Toscana (probably left by the other tourists) in the bookshelf in the main room we had a chance to know and see in Toscana more than we expected :)
