The apartment was very clean and spacious, bathroom had a nice shower and the kitchen looks well equipped if you want to cook but we ate out everyday so didn't use it.
It is a beautiful old building and location is excellent as it just just around the corner from the Ponte Vecchio so we walked everywhere.
The building was quiet but you could hear traffic on the street below, if you are not used to city noise this may keep you awake but it didn't really bother us. I would stay here again if visiting Florence.
