Giorgio and Romano are very good hosts. They were flexible with check-in/check-out - Romano arrived with the keys almost at the same time as we did! It's nice when you don't have to wait after a long journey.
We accidentally locked ourselves out of the apartment (our fault, we left the keys inside by mistake) and the hosts easily sorted it out (it didn't affect our trip at all).
The apartment is very clean, spacious and has air conditioning.
Vatican City is within walking distance and it's easy to get to the Colloseum via the Metro.
We enjoyed our stay and would stay there again if we choose to return to Rome.
