By far most luscious dorm I've stayed in-professional staff, great location with 5 minutes to State Opera House/metro station and many more. Very quiet this time around the year, only had to share with one other person throughout my 2-night stay there, however the staff mentioned it could get very busy in the summer.
This is the only dorm within the whole hotel and it's on the first floor. Huge locker with codes and also another safe in the locker to store your valuables. Inside the locker there were hairdryer provided and extra towels. Three sinks, two toilets and two shower rooms in the 8-bed dorm, however, the light switch to one of the toilets is not working, and the drain in one of the showers is clogged. I didn't mind at all since I shared with only one other person, but I would imagine it being quite stressful if it's a full house.
All in all it was a very pleasant stay, highly recommended!
