We really enjoyed staying in Maria's flat for over two weeks! All was as the pictures show. It was great that it is so huge and light and the terrace / outdoor area was great with the nice weather. We recommend climbing up the hill behind the schools, very beautiful area and views. The kitchen is not too well equipped if you really want to cook, but you can manage.
The only very unpleasant thing was that the floor was very dirty in the beginning especially with our children playing and crawling on the floor. Cleaning (without vacuum cleaner) took us one morning of our holiday.
General warning: our ebike, locked at a lamp post with an expensive lock, was stolen in the city during our first afternoon in Florence. If you want to bring a bike, it should only be a very shabby one.... :-(
