눉- Not a disadvantage, but beware that there is a (very small) fee if you want to get a towel from the hotel, toiletries, etc. However, this is expected from a hostel and can prove to be a lifesaver for a backpack traveller. (Plus, you can always use your own, nobody will forbid you or be rude about that.)
눇- The location is excellent; it's close to all the interesting sights and the neighborhood is slowly gaining a hip and artistic reputation. Unlike what other travelers have suggested, it is not a dangerous place to walk around after midnight (as it is filled with nice bars and lots of young people even on weekday nights).
- Clean room, with an ensuite (!) bathroom, and extremely comfortable beds. (Seriously comfortable, can easily be compared with a luxury hotel bed.)
- Morning breakfast buffet, which is included in the (very low) price! And there was still food left for people who slept in.
