I stayed at Mattia's place for about 3 months. He is the most welcoming, easy and friendly host ever. The house is just a few metres away from Piazza della Signoria, but in an area which is not too touristy. Light floods in the flat, which is equipped with all necessary appliances. Wonderful view onto the roofs of Florence and the Borghese palace. Lots of restaurants, bars and shops in the neighbourhood.... Definitely recommend, and I will be back myself asap!
