I feel privileged to have stayed in this home with my parents and two children. The apartment is spacious, bright, quiet, and comfortable. The host was very responsive to every question. There is a great grocery store (Conad) just a few minutes' walk. We got take-out pizza from Traditional Italian Pizza, also a short walk away.
We had mixed experiences on using the bus to reach the main tourist attractions, so definitely plan on extra time if you're going to the main sights (Colosseum, Vatican City, Pantheon, museums, etc) via public transportation.
