Tommaso was fabulous. The flat was great and in a fantastic area. There are great lunch options close buy(literally across the street from Mercato Centrale), lovely coffee shop with gracious hostess and a quick 10 minute straight walk to Firenze SMN train station. We had everything we needed. The wifi signal was strong and we had no issue. We left early in the morning and easily passed off the keys to the next door neighbor(Tommaso's family) so it was very easy and flexible to exchange keys.
One thing to note in that the loft level is only about 5.5 feet tall. This was fine for me(5'1") but not so fine for my BF (6'0"). The apartment is lovely and I would absolutely recommend it.
