One of the best backpacker experiences I’ve ever had. For starters, the stuff, from the front desk to cleaning, they have great attitude, they are helpful and kind. The location is unbeatable, you’ll be everywhere just in a 10 minutes walk. The rooms are spacious, with high ceilings, huge windows and good ventilation system. The whole place is super clean and tidy. Even if you stay in a mixed 12 bed room, you have inside 3 complete bathrooms, so, you don’t feel it’s even crowded. Inside the room you get a space for your belongings you should bring a locker. There’s a common kitchen and tables everywhere where you can sit and enjoy your meal or working. There’s also a laundry room, where there’s a laundry machine and a dryer, that work with coins. It includes the detergent and softener. If you search for other places to stay they may be a little bit cheaper but for sure for all the perks that are included (in other backpackers here they charge for kitchen supplies, there’s no laundry room, only one bathroom and a tiny one for lots of people, not near to important places, etc)… this is the best you’ll find in Oslo. 100% recommended.
