We (4 adults age 70) stayed here 4 nights May 18 to May 22, 2013. Excellent location, close (250 meters) to Metro station and 10 min walk to Vatican. Comfortable, roomy, well equipped, and great service. WiFi was useful and the apartment had everything we needed. The only downside was a small elevator which required multiple trips to get all our luggage. The elevator required that both inner and outer doors be closed by hand, and failure to do so rendered elevator inoperable for all users. There is only one elevator.
I would not hesitate to stay here again!
