I stayed in Melissa's apartment for four nights. Great location, quiet but only 10 minutes by foot to the main train station. The apartment is very stylish, as you can see on the pics here. You can see that Melissa is a style and design and architecture fan. And she shares her knowledge about it which is great as Oslo is full of architectural highlights. Melissa gives tips for the best dinner, coffee, museum, shopping experience etc.. Great place to come back to!
