Lovely little place on the outskirts of the "main" part of Rome. 25 min walk to Colliseum, 8 minute walk to the Piramide metro station and Roma Ostiense subway. Shower is TINY but works fine. It's a residential area- not much happening in the immediate surrounding area (1-2 restaurants 5 min walk away) but if you're looking for somewhere safe and quiet this is great. Host was available & responsive via email and graciously agreed to meet us at 1am (we just had to pay the 25e late checkin fee.)
Had a great time, and there's a washer in the apt!
