The apartment is located in a great area with most around and really central for all your sightseeing in Rome. That being said there was very little noise from the street which is rare in Rome.
The host was incredibly communicative and made the check-in process really nice after a little bit of a stressful flight.
One criticism is that the mattress is very thin and VERY soft so if you're are a picky sleeper with any sort of trouble sleeping on very soft beds probably not the place for you. There is also no soap/shampoo so BYO.
