Carmella's apartment is in an awesome location, it's minutes from the Coliseum. The apartment is a good base, simple and meets the needs of someone visiting Rome. You can walk to nearby attractions.
The air con is very loud at night if you're a light sleeper like me. The apartment is well insulated and you can't hear outside noise.
The apartment was clean and check in requires that you sign an agreement and also pay city taxes. The host Svetlana was nice and helpful at check in and out.
