Location is pretty good, 10 mins from Roma Termini and 15 mins from the Colosseum. The host was nice, allowed us to put our luggage down at 11am even though check in was at 3pm. He even offered us some cheese when he was cooking. Breakfast was good too.
However, the apartment is pretty old and run down. The room's heating wasn't working so it was pretty cold throughout the night. The bathrooms were the worst. Both had really bad water pressure and there was a period with no hot water (although the host quickly sorted that out for us). One shower had a door that is barely attached anymore.
