I didn't get a chance to meet Rosa during my trip but her brother, Antonio helped with the check-in (grazie for the coffee and recommendations!) and I spoke with her over the phone as well. It was convenient and relatively easy to reach her place via the metro and walk over to the apartment. There are food options all around the neighbourhood, including a supermarket and a really nice bakery just opposite selling coffee and confectioneries! If you walk about 15 - 20 minutes, you would reach the Vatican city where the museum and basilica's at. Rosa sets out breakfast for her guests daily (you get your own table and set of food), though I didn't try it and opted for eating out instead I really appreciate that she took the effort to do it. All in all, I really enjoyed staying here and can't wait for my next trip back to Rome. Thank you!
