i stayed in one in downtown san diego with a couple bro's (so we had our own room with 2 bunk beds and a table). we were like 28ish at the time and no one cared. our room had a fire escape so we took that to the roof at night and
and it was a fantastic few days.
my review is
price: a
comfort: c
communal bathrooms: f
summary: great if you don't mind dorm room showers for a few days and you don't plan on spending much time in the room
