During our stay, Silvina’s constant and quick communication/responses were very helpful. She even helped arrange for our son, who arrived a day later, to enter the apartment while we were out on a tour (and she, on holiday!), which was greatly appreciated!
The apartment was well suited for the four of us.
As many others have mentioned, the climb up is narrow and steep! If you are planning on anything larger than a carry on, it will be difficult to manage up the stairs. Or, if you are the least bit out of shape, this might not be the place for you—the actual apartment is good; the stairs might spoil it for you.
Otherwise, it’s in a great location (just down the street from the best gelateria in Florence—La Carraia) and 10-20 minutes’ walk to just about any site you’ll want to visit!
