We had a wonderful time at this stay. The location is not in the city center but very accessible to the Vatican (15 min walk) and the metro station (5 min walk) which will quickly get you to the main city sights. The airBnB is located on the 7th floor but there is an elevator that will help you get up. My family of 11 slept very comfortably here and there was definitely space for more people. We especially enjoyed the Espresso machine which made Americanos/ Cappuccinos/ etc. There is not a common space for gathering but there is a small dining room and we were able to enjoy a meal in there all together.
