Our stay in Niccolo's apartment was terrific. As a host he could not be any better, he met us at the apartment on a weekend showed us around the place, provided us with a phone, map and all sorts of information including the best bars and restaurants in Florence.
The apartment was much bigger than we expected, a decent kitchen eating area a comfy bed made the stay all the better.
The location is within a short walking distance to all major sights and Niccolo pointed them out to us on the map provided. I would definitely recommend to anyone that Florence is a great place to visit and hosts like Niccolo only enhance the experience.
