Tommaso's apartment is in a great location where we were able to walk to all the sight seeing spots in Florence. Our flight didn't arrive Florence until midnight, so by the time we got to the apartment it must have been 1 am. Tommaso arranged to have his friend Clara to meet us at the apartment to help us check into the apartment. Clara and her boyfriend was so kind to carry our luggage up the stairs. He left us a nice bottle of wine to enjoy. The apartment is well laid out, well equipped with everything we needed and very clean. My husband and I along with our two daughters stayed at the apartment for four nights in August. The A/C was definitely a plus and a must if you are in Florence in August. The fact that it has two bathrooms was also nice for a family of four. We didn't expect the many flight of stairs that we had to climb with our luggage, but we had heard this is quite common in old buildings in Italy (we did get help from Clara and her boy friend with the luggage up the stairs, but had to carry everything down when we checked out). Tommaso was super responsive and helpful with our questions about sightseeing in Florence as well as the apartment.
The only drawbacks (very minor) that we experienced, if I must pick on any thing, was 1) that the towels were kind of worn and stiff (though clean); 2) the shower pressure was very low and showers didn't drain well. Tommaso was very helpful when I messaged him about the drainage. He sent his dad to the apartment the very next day to fix it, but it was not much improved.
All in all, we cannot ask for a more lovely stay in Florence. We'd stay at Tommaso's apartment again and would highly recommend it.
