My brother and I stayed 3 nights at Domenico and Mario's place on our European backpacking. The room was spacious and comfortable. There was wifi, a kitchenette, and a nice back patio that we could use. Bathrooms were shared but that was not a problem for us. The center of Florence was about a 20 min walk away, which was convenient for us. We also made good use of the nearby grocery store.

The only real downsides to our room was that it faced the street and had no air conditioning. We visited in the summer so leaving the window open was necessary to stay cool, however, this also let in a good bit of traffic noise. I'm used to this so it didn't bother me, but it might bother some people. Other than that our stay was great and I would definitely recommend this place.
