Linda and her partner are really kind and helpful hosts. The room feels as private as a separate apartment which we appreciated. There is everything you might need for a short stay. It's just as good as advertised and we recommend it =)
The subway is less than 5 minutes away walking, you can reach the center in around 20 total from the door. It becomes a bit more inconvenient if you want to come back late since the subway stops around 1am and the busses options are a bit more limited, but the night bus still stops at Økern T.
