Easy check-in, desk 24 hours in case you need assistance. The room had lockers for your personal belongings, and you could purchase a padlock at reception (The locker in my room was broken, but I felt safe leaving my belongings in the room since I always took all my valuables with me anyway). The room had its own sink, and the bathroom and shower were in the hall, easily accessible. The bunk beds are pretty high, so look out for that if it could be a problem.
The kitchen and hang-out areas are spacious, and the check-in area and library are nicely decorated, which is always a plus :)
