Amazing!!! Waking up to the Duomo every day is truly a sight to see and feel. Okay, some things to consider for this listing. The stairwell is narrow and can be hard for some people, we were able to get by without difficulty, but I could imagine some may.
The location is next to the Duomo, so it can be loud with all the passing people. That being said, you are also surrounded by so many possibilities. Plan ahead!
The place is not soundproof, but there is a schedule quiet time at 23:00H
Overall, a wonderful place, I would go to this AirBnB again if I decide to come back to Florence!
