I can't say enough positive about our experience. We arrived a little early and were let in by the cleaners to deposit our bags as Donatella arrived to check us in and give us a little orientation.
The apartment is beautiful and the location is beyond spectacular. The square is obviously busy and noisy into the evening so non-city dwellers might find that a positive or negative. To us it was never an issue. I would tell anyone who wanted a quintessential Florence impression when they wake up in the morning, to stay here.
