My stay at Generator in Copenhagen was perfect. The hostel is super central. You are basically just a few minutes away from everything or the main metro stops. The reception is open 24 hours a day with super friendly staff and many speak Italian.
You can find everything inside in case you forgot something: adapters, sleeping masks, earplugs, cell phone cables, souvenirs, snacks, drinks, clothes, shower supplies, disposable raincoats and I think something else. I don't remember.
You can rent bikes, organize trips. There is a pub on the first floor, a nightclub on the ground floor, a giant terrace where you can play bowls, there are relaxation areas and 80s-style arcade video games.
Last but not least, the rooms are super clean. In a dorm for 8 there is a bathroom and 3 showers per room. And each floor has other bathrooms and other shared showers. The beds are very comfortable and I slept very well.
There may be some noise from outside but objectively the nightlife does not depend on the hostel and does not go on forever.
Highly recommended.
