The hotel is located on the Piazza del Duomo, on the fourth floor reached by a small, old fashioned cage type lift. It has a helpful, attentive, friendly staff and a great breakfast with views of the Duomo. It is located close to everything and is surprisingly quiet considering its proximity to the busiest attraction in Florence. Breakfast is a standard buffet but with good quality and quantity...and did I mention the views?
Our room was standard small but quite comfortable, spotlessly clean and the bathroom had a small shower but the water was always hot.
I would recommend Hotel Duomo.
