Niccolo's place is absolutely perfectly situated for exploring Florence. It is right next to the Ponte Vecchio and within walking distance to all of the major sights. We stayed a total of three nights, and upon arrival we were happily surprised with the location and the size. Even though there's no natural light in his apartment it is tastefully decorated and has everything you need for an enjoyable vacation. Niccolo even went above and beyond by providing us with a fantastic list of must see sites, his favorite restaurants and some general recommendations for areas to explore to get away from the tourist hot spots.
I would highly recommend to anyone considering Niccolo's place to just go ahead and book it!
