This little apartment was wonderful. It's located right near the Piazza Navona, and is right in the middle of everything you want to see in Rome - St. Peter's, Pantheon, Colosseum/Roman Forum, etc. There's a lot of great food places near by, including some amazing gelato at the Frigidarium.
The apartment itself is lovely. A small little kitchen and dining area with a spacious bed (fitting me at 6'5"!). The bathroom is small compared to American standards, but works just fine. It took us a minute to figure out the shower head, but after that it was great. The air conditioning worked just fine, and they included a fan to help blow cold air into the bedroom.
There was a bit of noise (music, people talking) on Friday and Saturday nights from the restaurant just below the window. We didn't notice too much noise the rest of the week.
Overall, it's a fantastic apartment with a great location, and I would definitely stay there again.
