Carlo's apartment is close to public transportation, and has a little patio out back. The aesthetic is rustic, and the apartment is dark and cozy. The bed is comfortable, and the kitchen is well-appointed. I think that we would have found it pleasant, but cramped, if our stay hadn't been dominated by any particular issue. Alas.
The biggest drawback to our stay was that Carlo was overseas while we were there, and he didn't have a caretaker lined up to handle issues with the house. We didn't have hot water for the duration of our stay, so taking showers became a real issue. We contacted Carlo, but his some of his responses were delayed because he wasn't getting regular text notifications (I presume), and the person who he said he was contacting to relight the pilot in the water heater never arrived.
