Gianpaolo's place to stay was a wonderful gem, and Gianpaolo is an outstanding host.
The apartment is really lovely - the bedroom was old-fashioned, in a really comfortable and homey way. The garden out back was great during afternoon heat, and afforded an excellent place to plan a day's outings.
Gianpaolo was attentive, quick to respond to questions, and eager to chat about travel, things to do about town, and cultural exchange. He set out small things to welcome his guests, from useful maps, to local sweets, and homemade preserves!
We were very pleasantly surprised that the apartment was so well stocked with small attentions (shampoo, laundry soap, spices, olive oil, etc.). By the end of our stay, we hoped we could have stayed longer. (Also, the best gelato place in Florence happens to be down the road.)
We would definitely recommend Gianpaolo's place to all our friends.
