Marisa's place was was really comfortable, spotlessly clean, and (mostly) very quiet, a good place to rest at the end of a long day walking around Rome. Marisa was also super friendly, flexible and attentive. However it wasn't clear that the place is in a fenced compound and only accessible (to people without keys) from Via Ardeatina (which has fast traffic and bad/no pavements), NOT from Via Luigi Capucci, so thank God for the nice lady who let us through when we were semi-lost trying to find another entrance via the park in the complete darkness. That said, there is a bus stop right by the entrance on Via Ardeatina, so for anyone arriving by bus it's perfect.
