Paola's place is one of the few on AirBnB in Rome which is actually decorated and furnished to evoke a sense of Rome's history and romance; the original 17th century ceiling is complemented by Roman floor tile, Renaissance-style iron window grates, and furniture and wall decorations to match. It would have been nice to have been able to go out in the small courtyard, with its quiet calm, slanting light and grape arbor, but it was still pretty nice to open the window and enjoy it from inside.
In practical terms, Paola's place is in an excellent location right between the Termini train station and the Colosseum, and it's a back apartment on a side street, which makes it very quiet and enjoyable. It's a perfect size for two people, as we were. I would not try to have more than four there, and even that might be a stretch for more than a couple nights. One thing I would mention is that the street is somewhat hilly, which was no problem for fortysomethings like us, but which might present a problem for some retirees.
