It was a real pleasure for us (two couples) to stay in this wonderful apartment. Paolo was a perfect host. He answered every e-mail request very quickly, arranged all necessary details in advanced and welcomed us at the apartment on time. Additionally, he gave us a thoroughly guidance through the apartment and provided us with touristy and culinary recommendations (make sure to check out at least some of the recommended restaurants and bars - both in the immediate neighborhood and in the inner city - they are all excellent). The apartment was exactly as the images suggest. Both bedrooms and the living room were huge, everything was clean and nicely decorated and - best of all - there's this amazing roof terrace to your exclusive use. I would solely take this apartment for this roof terrace. We had breakfast and dinner there while enjoying and amazing view over the city (with the Colosseum, St. Peter's Basilica and Monumento Nazionale a Vittorio Emanuele II in the center of your view). Especially at night, having a glass of wine and admiring the beautiful lights of the city is way better than spending your time in a crowded bar in the city). Furthermore, the apartment is perfectly located in the center of Rome, only 5 minutes from the Colosseum. You can easily walk all major sights and in our five-days stay we only took the metro (which is not far away) only once to the Vatican. The neighborhood is very nice with a bakery and a mini-market just across the street and fantastic restaurants and tratorias in walking distance.
The only negative thing was that Paolo told us on our first day that we can have the apartment to our own on our last day and that we don't have to check out in the morning. But at 10 am they wanted to start cleaning the apartment. We arranged that they come back at 11 am and that we can leave our luggage until we leave, so this was no major problem.
I would definitely recommend this apartment and Paolo as a host!!
