It is a good choice to stay in Rome with Paolo's. Paolo's place is comfortable and in a very good location that is walking distance to a lot of historical spots such as Church of Sant' Agostino, San Luigi dei Francesi, Sant'lvo alla Sapienza, the Pantheon, Trevi Fountain; it is also near to shopping area. Colosseum and Vatican are just 10-15 mins away by car.
Rome traffic can get very bad in peak hours, so it is very important to get a place that is convenient and accessible to most of the necessities, as well as the places that you want to visit!
The other star point for Paolo's place is that there is a very nice gelato shop right at the ground floor of the building, and if you want to get a local Italian coffee for the morning, there is a cafè just next to the gelato shop :)
