The CasaRiz apartment is on the third floor of what appears to be a mixed-use apartment/commercial building - but it is quiet so sleep is not interrupted. The elevator is very small - about the same size as one of the 'Superman' style telephone booths. It can hold two standard people or one person and one piece of large luggage at a time. The kitchen is best described as being in a closet - very compact with a microwave oven, stove-top, bar refrigerator, and sink. The hosts live on the same floor and are very helpful, friendly and available. The actual location of the building is on a sloping street with restaurants, shops and Vatican Museum entrance all downhill - which is not a problem. The downside is coming back to CasaRiz as it is all uphill - we took a taxi more than once (but we are in our 70's). It is a great location for accessing the Vatican as it is only a 15 minute walk away. We took taxis to other tourist spots although local buses and the subway are all nearby.
