We stayed here twice while visiting Oslo on the same trip for 1 night each. You will be pretty much on your own in the hotel - it has very minimal levels of service and staff which is a great thing. Even then the rooms are very well maintained and extremely clean. The location is perfect as it is very close to the tram station and you can even walk to the Oslo Central Station which is the heart of all transport in Oslo. Places like Aker Brygge are about 15 minutes by tram. There are several convenience stores nearby and on the street parallel to Storgata there is the youngstorget square which has several nice cafes and bars.
If you are on a budget trip and do not want to live in a hostel then this is definitely your best bet!More
