When Europeans say "Adult Only" they actually mean couples, not friends sharing rooms. While the hotel is very nice, the rooms have glass exposed showers and bathrooms, so if you need a bit more privacy, this is not the place. And the loghts from the bathroom and shower area light up the rest of the room so be warned if you don't want to wake up your roommate in the middle of the night. Otherwise, great if you want a romantic weekend with your spouse or significant other...
