We had a wonderful time staying in the flat. There's plenty of space, and lots of comfy sofas (we sat on one each, just because we could). It has a very relaxing feel, and there's a fantastic gelateria a few doors down. Paolo and Mariano both answered messages really quickly, Mariano was really friendly and helpful in showing us around the flat, and with recommendations of places to eat. I would definitely stay there if I was in Rome again with a group of friends.
