We had a lovely stay at Lorenzo's apartment over a long weekend in November. The kitchen and bathroom are small, but the bedroom is a great size, well provisioned and with a huge, extremely comfortable bed. The location is superb and all major sites are accessible with a short walk, or in our case, v fun e-scooters that can zip you around in no time.
Two things to mention: the kitchen was slightly understocked, with no kitchen utensils or basic ingredients (olive oil, salt and pepper), and the hot water in the shower doesn't last particularly long. You'll struggle to have both of you have a hot shower before it goes cold.
Apart from that, it was great and would thoroughly recommend the place.
