We are just back from 6 days spent in Giovanni and Valentina's apartment and we truly loved it. There was ample space for my 5 friends and I and it was great that each room had its own bathroom. There was an issue in the master bathroom but Giovanni and Valentina did their best to solve the problem quickly and even offered us a refund for the trouble. The weather was really nice so we were able to enjoy the terrace in the evening.
The apartment is beautifully located right in the middle of everything. You can basically walk everywhere and there are tons of restaurants in the neighbourhood. We recommend Mazz for breakfast as they are very friendly and sfogliatelle are served fresh from the oven in the morning.
Communication was great at all time!
