We had a brilliant stay at the apartment! Everything was exactly as described - neat, compact apartment with everything you need, kept spotlessly clean, and in a fantastic location, right by the Santa Croce. We walked everywhere, didn't get a bus once, and there are some nice little coffee shops and a handy supermarket within a few minutes.
Niccolo was a great host, he gave us excellent restaurant recommendations and a really useful map of the city and responded really quickly to any queries we had. The bottle of wine he left us was a lovely touch and delicious too!
I would definitely recommend both Niccolo and the apartment, and would book this apartment if I ever go back to Florence. Big thumbs up from us!
