We loved this hotel! We stayed in the Library Room. Big by U.S. standards. Huge by European standards. Comfortable (true) king size bed. Friendly staff. Rates were pretty reasonable.
What set this hotel apart, however, we're the rooftop terraces - one overlooking the Duomo, the other the Arno River and bridges. Huge areas, self serve bar and phenomenal views. Can't imagine better views from a hotel in Florence!
