You won't find a better location near to the main sites while not being on a street overcrowded by tourist. The building is more modern than many of the buildings on the street which means the hallways are wide and the elevator won't make you feel like you are in a can of tuna.
Comfortable beds and room enough for the 4 of us to be able to relax once done with our day exploring the city.
Saverio is a great host. He went out of his way to answer all of our questions providing details that made the difference between a good and great visit to Florence.
One suggestion; be sure to ask for directions on how to use the washer/dryer. It's nothing like we've ever used here in the States so best to ask for guidance.
