We stayed in this apartment for four days in November as a group of 2. The location of this apartment is truly outstanding to visit Florence. You are close to all the sights on each side of the Arno river. The apartment is situated on a high floor, but the stairs are spacious and comfortable, so they are not an issue as long as you can go up a few flights of stairs. The apartment was super clean. We had an issue with the heating system (we had hot showers but cold radiators), which ended up being resolved by clicking a button on the boiler, but getting help took more time than I would have hoped on a cold week in November. The host was friendly and as helpful as they could have been, they even turned on the convertible AC for us while the boiler was getting looked at. Once that got sorted, the regular heating got fixed and I can confirm the heating works well, even in the winter!
