Our stay with Vittoria was ok but there was a few issues. When we arrived Vittoria had left the key with a friend due to being out of town. The friend had misplaced the key and initially told us that he had given it to someone else. After the travel and walking through the heat we didn't need the stress of thinking someone else was in our rental.
Eventually he figured out that he had just misplaced the the key any we were able to enter but it was not the smoothest check in experience. We had an issue with the AC when we got inside with the AC remote not responding to input. I messaged Vittoria about this who's response was to tell me to try using the remote. Maybe it was a language barrier issue but it came off condescending. Regardless I fixed the issue be removing the remote batteries and replacing them after a bit. On the topic if AC it is located on the far side of the apartment and does not really reach the bedroom but a fan was provided which helped.
My wife's sister had the sofa bed which she stated was very uncomfortable but sofa beds tend to be bad anyways. We were also left with 1 half used toilet roll for 3 adults which was not very accommodating.
The location is very good, located between the market and the Basilica San Lorenzo. There was some free live music at the Basilica in the evening which was nice. The main bed was reasonably comfortable. The steps leading up to the apartment are fairly steep and might be difficult for someone with limited mobility.
All in all it is not a bad apartment but there are better places for the money. I live in Naples and have stayed in Florence many times before. On my next trip I will be looking elsewhere.
