Christoffer is a wonderful host who cares about his guests. Not only he responds quickly any questions or concerns you might have, but also makes suggestions, e.g. what to visit or how to get there, etc. We were able to see a blossoming lotus in the Botanical Garden, a very rare occurrence in Norway, because Christoffer read about it in the paper and promptly let us know.
The apartment itself is close to all means of transportation so it is easy to get to all the major attractions. You can even walk to some.
The bed is big and very comfortable. The kitchen is equipped with everything you might need to make meals. There are a few supermarkets/grocery stores nearby. Overall, it is a convenient, clean and wonderful apartment. We highly recommend it as a great place to stay as well as its owner, Christoffer, as a superb host.
