I had a nice and pretty relaxed stay at SleepCph. It's not in the middle of the city but still pretty close and has easy access to it even by foot, plus it was also a plus that the airport is only 15 minutes away by metro.
The room actually delivered everything in the end, it was clean and I think it is a good solution for people who need to stay a night or two and don't want to sleep in a bunk bed room. The bed seemed a bit too soft to my preference; other folks might actually like it.
There were some strange minor issues regarding hygiene meaning the showers at the first floor seemed really old and uncomfortible - with no proper shower head extension installed on them-, so I heavily recommend using the ones on the ground floor, but I also had to note that there were no shower gel and shampoo included there so consider bringing your own.
Communication and check in/check out were super easy and free luggage storage is available till 11pm on your checkout day.
