We stayed at Alessandro's place couple of weeks back. It was four of us and as per the listing, it seemed like a good space for the group. Alessandro was always responsive and available and the check-in was smooth. It was the house itself that didn't meet our expectations.
The biggest problem was the lack of ventilation. The apartment is divided into two floors and there is just one window which didn't open. So the place smells and feels damp.
Secondly, having visited Rome in July, air conditioning was important but did not work well at all. The air conditioner kept shutting down every five minutes and since it was the only way to cool the entire house, it made being in the house quite uncomfortable, especially in the bedroom above. The table fan also didn't work. I informed Alessandro of both these issues on day one itself and he visited that evening, but none of the things were fixed during our stay.
Also, the sofa bed in the living area was not in a well-kept condition and one-half of it was just not comfortable to sleep in. All things together, make it impossible to have a sound and comfortable sleep in the apartment.
The bathroom sink leaks and since there is not ventilation, the floor took hours to dry.
Despite having a good location, I would not recommend staying here, at least during summer.
