We had a great stay at Marella's place. We arrived at the square a bit early than planned and we were able to easily check in early which was great. The kitchen was stocked with everything we needed. The flat is in a good location right by the square and we were able to walk to everything in Florence. It was quite noisy at night sometimes due to the outside nightlife, but I don't think that's something you can avoid if you want to be centrally located in the city. The flat has good double windows, but if you are a light sleeper it is still loud on some nights. Overall, we had a great time and I would recommend to stay here when visiting Florence.
