While it is one of the cheapest hostels you can get in cph (possibly the cheapest) with an absolutely excellent location and nice enough staff its audience is definitely more backpackers or young people looking to party. Not suited for families and couples that want a stable base to crash.
We had to endure a 3AM party in the neighboring room, which the following day was met with a "well, that's unavoidable in a youth hostel". I doubt the accuracy of that statement, but not that this could be a great place for the mentioned groups.
Hallways have a weird smell and are generally dirty. Bed had weird stains.
