We stayed at Alberto's place for a quick stop in Rome. The location was great for this since everything was close by. You can walk to the Vatican within 10-15 min and take the buses to the main attractions in case you don't want to walk.
There are restaurants, supermarkets and everything you need within 2 minutes walking. We love the rooms for sleeping since the beds were comfy and the room was really dark at night, the place is peaceful, there is not any loud.
He also responded to every question we had and helped us with an earlier check in.
In general everything was great, I recommend this apartment for your stay in Rome.
