This place was fantastic! I was lucky enough to have the chance to stay for two weeks in this gem of an apartment. Espen and his family were very kind and helpful, but I also felt like I had my own space for my stay. Everything was beautiful and comfortable. The kitchen was exactly right: small enough that it didn't overwhelm the apartment but more than functional enough to cook a meal for a night in. There were also plenty of comfortable places to work while I was at my conference.
The apartment is a little bit of a walk or bus ride outside of Oslo center, and wouldn't be right for someone who wanted to be right in the middle of downtown. But it's perfect for someone who is interested in a quieter neighborhood while still having the center of Oslo easily accessible.
