We stayed only one night with Riccardo. The room was spacious, clean and brightly decorated, with a balcony and big window - the photos are accurate. All in all very agreeable. The bathroom was smart if modest on how water and water pressure. This may have been due to 'works' in another part of the building.
The block itself is very presentable with a spacious entry hall and smart lift.
The metro is very near. A two minute walk. The area itself is pretty charmless - suburban. There is an outstanding mozzarella shop just over the road which makes up for all the ordinariness of the area. That said the metro link into downtown Rome is very regular and fast.
