The apartment is just 100 m from the Vatican Museum.
Restaurants, bakeries, supermarkets are closed to the apartment. For the Metro, you have to walk but it is not far.
I think it can be hot in the summer. We closed every morning, before leaving the apartment, the shutters. At night, the apartment was not hot!
Even if a tourist area, it is not noisy at night.
Andreas is a great host. Our flight was delayed. We arrived late at night (midnight!) and Andreas waited for us. He organized the transfer from and to the airport. He answered our messages.
I fully recommend Andreas' apartment.
