TLDR: I went for one night, and it was perfect
The bus to the airport is 85NOK, which is an acceptable price
Very friendly staff, nice breakfast, nice bedroom, nice toilets. I stayed just one night but it was pretty good.
WiFi worked great. There's a bus to get to the airport, price is correct.
It's not a 5* hostel, but it is perfect for my use-case: staying one night :)
Getting the room keys was quick and easy, getting the bus was also easy, everything easy!
Its very silent.
The toilets have good water, cold/hot, clean towels and shampoo was also provided.
So yeah, I recommand.
Also the staff is good, they welcome any question and all, just perfect. They talk well in English if you only talk in english like me hahaha
