The apartment is very beautiful and clean, the location is wonderful and the host is very helpful and easy to keep in touch with. We were two couples, and there were two bedrooms and two separate bathrooms, so that was very luxurious. The only point of feedback is that the apartment is situated above a bar, so keep in mind it can get noisy in your bedroom during the weekend.
Otherwise, when visiting Florence, I can highly recommend this airbnb, and I would definitely stay there again myself!
