The single room that I got is OK for a budget traveler. It's very small, has it's own bathroom, a small TV. Everything you need, basically, but also very basic. It's also a bit worn, but that can be acceptable if the price is low. Breakfast is also basic, but OK. They serve hard boiled eggs.
The problem is that Trip.com charged me 596 dollars for 2 nights at this hostel. That is not a price that fits this kind of accommodation! The price at ********** for the same room with check in one day later was half this price. I don't know whether Trip.com or Mosebacke is to blame for this price, but someone took a huge advantage of the shortage of hotel rooms in Stockholm at this time.
