Great apartment, great location, great host. The apartment is a five-minute walk from a metro stop and numerous bus stops, two minutes from a grocery store and decent restaurants, and 15 minutes from the Colosseum. It's clean, modern and pleasant. Just be prepared for hiking up four flights of steep, narrow stairs. But in exchange for the stairs, you get a nice little balcony, which the lower floors don't have. Giulia was responsive and friendly. I didn't get to meet her in person, because she was away during our stay, but she had her friend Andrea stand in for her - he met us at the front door on our arrival, and was very helpful. We had a little problem with the cooktop and he responded immediately to a text asking for help with a video showing us how to re-set the gas line and an offer to send a repair person if that didn't work (it did work). I'd definitely stay here again and highly recommend it.
