We turned up near 12am and were still able to check in and the location is very good, walkable into central Stockholm. The vibe is very unique and hip. The option to pay a little bit to check out at 1pm was most welcome as well.
However there were a couple of downsides - I don't know if it's because of the weekend, they had karaoke nights near reception and the music was so loud, I could hear it on the 6th floor and it continued into the early morning. The windows seem to be single glazed so I could hear the street traffic as well. The toilet is on the small side and it's quite weird as a customer having to put bed sheet on the mattresses ourselves. There were no chairs or tables to put stuff on and the sockets are all located at very strange places. One by the door is more or less near the floor, the one next to the single bed is hip height and the most bizarre one is the one above the bed, leaving wires hanging everywhere and risk having the stuff fall onto your head.
