Great apartment in a great location. This was my first time in Rome, and was able to walk everywhere from this apartment. Marcella was very responsive and a great host.
As many others have mentioned, the only downside is how noisy it gets at night. There is a popular bar across the street and the music and people are pretty loud until 1am every night. Marcella kindly provided earplugs which helped, and I wasn't really bothered by it. Just a warning if you're a light sleeper.
