Ingar was a great host, very helpful with directions although it is pretty easy to get to his place. A good location, near tram and bus lines which can take you all the way to the maritime museums on the far side of the city, you can also walk to downtown in about 30 minutes. The space is amenable and comfortable, though people who need lots of personal space or have trouble with stairs might not find it so, but for me it was a great way to see Oslo.
