Silvia was a great host, very communicative and helpful. The apartment itself is situated in the heart of Monti. You can walk to the Colosseum and many other attractions. The room has two sofa beds (no actual bed) - this was a key piece of info that I missed from the pictures as the listing did not spell it out. Nevertheless, the sofa was comfy but a little squeaky and run down. The bathroom was a little small and dated, and the bathtub was a little grimy - this may bother some people. Parking in the area is difficult, you can enter the zone after 6pm and park within white markings for free, or within blue markings and pay per hour. Do not park within yellow markings, even if recommended by the host - we did and got a parking ticket. Not her fault. The internet was also a little slow and the wifi signal very weak - it did not reach the bedroom.
To sum it up; it was convenient and comfortable, and a lively part of Rome. If you want a quieter, modern, more refined place, this may not be for you. It did the job.
