If you are looking for a stay near Vatican City, you can’t find a better deal than this apartment. Maria’s place is spacious, clean, and 10 minutes walking distance from the Vatican City. It is also about 10 minute walking distance from the subway station.
Just to note, the apartment is right above the flower wholesale store and is behind a school, so it can get a little noisy. If you are used to a little noise outside during sleep, you should be fine, but if you are a light sleeper, you may want to reconsider.
For me, coming from a metropolitan area, I am used to outside noise during my sleep, so had no issues.
Maria cannot really speak English, but she is extremely nice, and left some yogurt, bread, and fruit for us. A little google translate goes a long way!
