Super clean, a little complicated to get into at first, it’s a place to sleep after a long day and it was great. I would recommend talking to them about how to get in before you get there, it was a super hot day for us so it was tough when one of the individuals kept cutting us off on the phone and hanging up while we were trying to figure out where to go.
Overall though, I would definitely stay again if I were to do more activities near the Vatican, it’s the perfect location for that!
