Great place to stay!
I really enjoyed Nicco's apartment. It's super clean, super tight and it has seriously the most comfortable bed in Firenze! I swear to you, if you're looking for a very comfortable place to stay nearby the Duomo (10 mins walk as much) it's the place for you! Also there are very delicious restaurants to eat near to the apartment and the feeling of being in a very Firenze neighborhood it's there.
