The apartment was a nice location, clean and satisfactorily provided all we needed. Host were nice.
A bit small for a family of 4, but we made do (1 bed and 1 sleeper sofa). Location is certainly the best part as it is just a 5 minute walk from the Duomo. If you have issues with stairs, take caution. The apartment is on the 6th floor and several times the elevator was not functioning. The place was immaculate and they provided hotel size soaps, shampoos, etc. Due to location, it is not quiet at night, but that was expected staying in a big city.
The hosts are very nice, but we did have issues with check-in as they wanted us to download their Sweet Inn app upon arrival. Would be best to request check-in instructions provided via Airbnb.
