Marcus' apartment is in an amazing, quiet and historic neighborhood. Although you are just a block from a wonderful street with many shops and restaurants, the house is extremely peaceful and secluded. The parking is also a huge benefit for a city apartment.
The unit is very new and clean, with a beautiful bathroom and nice amenities. The couch is not full sized, however, and even when extended is small for anyone over 5' 10". The elevated sleeping space is very nice, though, and surprisingly spacious.
Marcus was extremely responsive, although our schedules unfortunately did not allow us to meet in person.
A very recommended apartment for exploring Oslo!
