Do not be deceived - this is NOT a hotel. It is a hostel. I booked a room for two friends and me, and I noticed that it said "3 persons, shared bathroom." While this may be explicit enough for some, I took this to mean that there was one bathroom for the 3 of us, not that we would share a bathroom with the rest of the hostel. The bathrooms are also not separated by gender, which made us rather uneasy. The rest of the hostel (staircases, exposed construction, un-enclosed elevator, reception area) was pretty grungy. Room didn't seem very clean...dirt/dust on floor and I had a unshakeable feeling that the curtains hadn't been cleaned in a very long time. Beds are Ikea and not very comfortable. Our safe in our room did not work either, which was disconcerting given how unsafe the entire hostel seemed. Thankfully, once we realized this, we were able to work with Hotels.com to lock us in to only one night of our 4 night reservation without any kind of additional fee, so we found other accommodations for the remainder of our vacation.
In short - if you're down to rough it, maybe this place is OK. Just not what we expected. Though Stockholm is a super pricy place, even the comparably "low" price of the hostel could not be justified.
