When we checked in, the lady who met us outside told us that the previous guests had broken a glass in the shower and that it would be fixed later in the afternoon. She was very apologetic, but the bathroom was indeed a mess with a broken glass door shattered on the floor. The bed also still had the previous guest's bedding and it wasn't clear that the apartment had been cleaned at all.
We dropped off our luggage and headed out to explore Florence, but both issues were surprising unsolved when we got back later in the evening. At that point, I needed to call a series of people to request that the apartment be cleaned. This was complicated by the fact that this apartment is managed by some sort of company, so I rarely talked to the same person. Someone did eventually come by and clean the apartment and the remove most of the broken glass.
After the initial check-in drama, the rest of our stay was good. The shower never got a replacement door, but the rest of the apartment was great. The view from the balcony and the location can't be beat.
