My friend and I had a lovely time staying at Magne's place. Magne is a fantastic host and a wealth of knowledge about Oslo.
We arrived before check in and Magne helpfully arranged for us to be able to store our bags at the house so that we could explore Oslo without luggage. He also invited us in for coffee and a lovely chat.
The space itself is as it is described. The bed is very comfortable and the apartment is clean and cosy. It is in a quiet neighborhood that is well connected to public transport but also not too far to walk into Oslo if the weather is nice.
We would highly recommend staying with Magne to anyone visiting Oslo!
