Flat is in a great location for the main attractions in Florence, and we loved having enough room for our party of four to spread out. Florence had insanely hot temperatures while we were there (102F!) but the AC here worked perfectly. Very clean, especially bathrooms, having a washer was great, and checking in and out was extremely easy. Yes, there are a lot of stairs. I would not recommend this apartment to anyone with mobility challenges or who simply doesn’t have the energy to deal with them, especially with luggage. But that is very clear in the listing and reviews. The decor is elegant but spare and we were very comfortable.
