I went to Florence for a conference and stayed in Tommaso's apartment for a total of three nights and three days with a friend, we found it perfectly located (it's really only a 5 minutes walk to the Duomo), very clean, colorful and welcoming. No disappointments, it looks exactly as it is in the photos, the only slight downside is the height of the attic where the bed and bath are located: the ceiling is unfortunately really low. It must be said though that Tommaso was very friendly and always available when we needed him, he waited for us even if we arrived late in the evening to hand us the keys and was very helpful before hand with tips on garages and parking lots. I would certainly recommend staying at his place.
