We had an amazing stay at Andrea's apartment! The apartment was in a great location. It was right next to the train station and close to all the major attractions in the city. It was a private residence which required you to go through 3 different doors before you can get into the apartment which felt very safe. The building was well maintained and had beautiful decor (e.g. marble floors) which was appreciated. The apartment itself was very spacious and extremely clean. It had a lot of natural light which was great. The washer was very easy to use so we were able to do a couple of loads of laundry there. The bedroom had a separate AC unit which made the stay very comfortable. The living room / kitchen was very spacious and clean. The bed sheets, pillow covers and towels smelled very clean which made the stay felt very comfortable.
The only thing that did not work well was the blackout blinds in the bedroom. The blackout blinds require you pulling this pulley which was very hard to pull and it did not close all the way. We had eye masks on which helped otherwise, you would get a lot of sunlight into the room in the morning which would make it hard to sleep.
My only other minor suggestion would be that there should be more local recommendations on where to eat (restaurant recommendations) and where to go which would make the "hosting" experience of AirBnB more complete. Andrea had a booklet of instructions on how to use the things in the apartment etc. but overall, it lacked the "host" experience and local insights to Florence. We also asked him for restaurant recommendations but he did not send this list to us. As a result of that, we gave this a 4 star but could have been a 5 stars had we had more recommendations from the host.
