We were welcomed with open arms by Claudio to a lovely boutique hotel. The spaces are stylishly decorated, snacks and coffee/tea are provided in the common area and the room was private and quiet. The only disadvantage I can think of is the high humidity in the room (accompanied by a moldy smell), but air conditioning with a dehumidifier option is available and the window can be opened. The location is fantastic, just a few minutes away from the Vatican and metro. The street parking is limited but there's a small street-level parking garage to the right of the AirBnB where we parked our car for €30 for 24 hours.
