Me and my friend spent two nights at Naike's place. Apartment is quite big and has two bathrooms which is very comfortable. Room is also spacious ( great ceiling :)). Take earplugs if train sounds bother you a lot (tracks next to the building) however after whole day of walking we were so tired, that we didn't even hear them. Communication with the host was great and also area was pretty calm. There is a Penny market nearby which is a big plus. Book a room and have a great time in Florence! :)
