We were very glad to stay at Matteo place during our visit to Florence. Matteo and Gigi are perfect host. We arrived late at night, but it was not a problem for him, he met us and gave as all instructions.
The room is very clean and comfortable to stay. We had our own bathroom.
As for location, it is totally ok to explore the town. There are a store near to Matteo's place. We could use the kitchen and it was very comfortable for us.
Thus, if you want to explore Florence, Matteo's place is a good place to stay. Totally recommend:)
