Sahnofar is a very caring host, offers help and communicating is very easy.
And the appartement is perfect for visting Oslo. A Bus station right on the corner, a tram station just a 2 minutes walk away and subway station Nationaltheatre 10 minutes away. This is also great because it is a station of the Flytoget train from the airport. Within a 1o minutes walk you reach Aker Brygge, the castle and Karl Johan Gate.
The appartment offers everything you need, has a nice, modern style. I would rent it again!
