Easy check-in and out, great location, everything clean and in working order. Spacious, private, quiet room (we had a private room for four). A little strange that our room included a kitchen but had no pots/pans/dishes/utensils of any kind. This was our first hostel stay so I'm guessing guests are expected to either bring their own or pay extra?
Towels and linens and soap in wall dispensers (at the bathroom sink and in the shower) were all included. Huge bathroom.
We stayed on a Friday night and it seemed busy enough in the main areas but I was amazed how quiet our room was the entire length of our stay.
There's a Kiwi grocery/general store right next door, very convenient! And plenty of parks, cafes, etc. within walking distance. We also walked from and to central station, maybe a half-hour walk? But local transit is probably great too, we just didn't use it our one day in Oslo.
I would absolutely come back here!
