Jo's place is exactly as described. It is very easy to get to by bus from central station. It is warm and cosy with everything we needed for a relaxed stay. Jo and her daughter were very welcoming and helpful and communication was very easy.
We had a pretty busy couple of days seeing as much as we could of Oslo so it was lovely to return to Jo's knowing it was in such a quiet and beautiful suburb. The place was very clean and comfortable. Close to museums but a short bus or ferry ride into the centre of the city. Would highly recommend.
