The appartment is located a couple of metro stations away from Vatican and about 8-9 stations from the central Termini station, which is fine because metro and buses run often and you can get to the historical center fairly quickly (assuming that's what you want to explore). The appartment is equipped with all necessities for cooking. The owner is very nice. She's amazing. She has a small booklet explaining stuff and showing how to get by, where stores are located etc. Super helpful! The biggest downside is that you can sometimes really hear the neighbours. That being said, all things considered, we enjoyed our stay and would recommend this place.
