We loved our stay at Malmøya. The appartment has a beautiful view to the water. It‘s quite small, but also very cozy. Everything you need is there. You can cook for yourself - there is also a kitchenarea with a fully equipped stove and oven. The surrounding area is beautiful and quiet, very peaceful. Oslo is also easily acessible by bus (bus stop 10 minutes away): once or twice per hour you can go to the city centre by bus, it‘s only a 15 minutes drive.
We can recommend Mortens place very much - he was very friendly and helped us out fast whenever we had any questions!
