Thanks for the stay Fabrizio and Alessandro!
The apartment was exactly as described, incredibly elegant in a cool and unusual old hotel. I was a little unsure of the time we would be booking in, as we were planning on visiting Procida on the day, but Fabrizio and Allesandro were very accommodating and understanding of my changing plans. After a bracing walk up from the Port, Alessandro met us and check in was not a bother.
The rooms are very clean, with air conditioning and a beautiful bathroom. There is a small window with a view onto the courtyard, and does feel very much like a hotel room in a lot of ways. A nice change from the intensity of the city!
