Maurizio is a warm and generous host, and we enjoyed staying in his apartment. It's a great choice!
It's in a good location, on the quieter side of the river but in walking distance of the sights. (It's particularly well-situated to visit the Masaccio frescoes at the Brancacci chapel.)
The flat is cosy, with an internal living room and a bedroom facing onto a quiet street and a park. It's got a nice homey feel.
As other guests have noted, Maurizio is very generous with the snacks and supplies. We also particularly appreciated his collection of guidebooks to Florence. We used his copy of the Blue Guide to find our way around and find good places to eat. Highly recommended!
One last recommendation: try Da Angelo Gelateria, on the way to the Ponte Vecchio. There's a lot of great ice cream in Italy, but this is some of the best we had.
