Christina's apartment is fantastic. We had a group of 4 and really enjoyed staying there. In terms of location, Grunerlokka is great if you want to be near some of Oslo's hip bars and restaurants. Christina made it very easy for me to pick up the keys, and the apartment was perfect when we got there. She left some useful info on getting around and even a guidebook.

The deck is absolutely amazing too - perfect place to enjoy a glass of wine.

I'd highly recommend Christina's place if you're looking for a great place to stay in Oslo.
