I got the private en-suite room. The view was beautiful from the window as I was so high up. The room is small, but everything you need is included. Wi-Fi is fast and connection is also perfect. Staff are friendly and aren't afraid to smile and offer help. Even though there was a trainee at reception, she still tried really hard to be hospitable and inform me of all the information I needed, without being shy or dismissive. The reception/bar/restaurant is separate from where you'll stay, but it's only next door. The lift looks dodgy, but it's safe.
The location is perfect, it's around a 7 min walk (if you're a fast pacer) from the Copenhagen Central Station (København H), which means you have plenty of choice for fast food/restaurant, high street shops, sightseeing or travel.
Only thing I didn't like was the fact that the toilet roll holder and sink is on either side of the toilet in such a small proximity, so you literally feel cramped if you need to use the loo, especially if you're a bigger person. It's a wet room format, which is fine, but the shower head (which is on the ceiling) and the drain is so close to the toilet. So you kind of have to stand near the toilet to shower, even though there's much more room in the bathroom. Apart from that, I really can't complain for what I paid.
If you don't like young people and noise, then I wouldn't recommend, because I could hear them up and down the corridors all the way up til the early hours of the morning, but it's a hostel so, it's to be expected.
Something extra for anyone who is staying here - if you want to visit a large shopping centre or shopping mall and you don't want to take the train, take the 7A bus from Tivoli Gardens area and get off at Fisketorvet. Literally around 3 stops :)
