We had a great time! Andrea was super helpful throughout the entire stay. The location near Piazza Santo Spirito was awesome and we liked being a bit away from the city center. Great restaurants include Borgo Antico in the piazza, Trattoria Casalinga, the gelato place nearby and Marina di Santo Spirito.
A few things to note: It's on the 4th story, so be ready to walk up and down stairs a lot. Also there is only A/c in the bedroom, and it can get quite hot in the kitchen in July. The mattress wasn't that comfortable either, too firm for a side sleeper like myself. The apartment has everything you could need to make coffee, cook, etc. The location is really pleasant.
Andrea was a great host!
