I booked Magnar's apartment for a week on behalf of my family who were coming to Oslo to visit (2 adults, and three teenagers). The apartment was perfect. It is a very short distance to public transportation and there a couple of very nice walks in the immediate neighbourhood (particularly going up Husebyskogen). The interior of the apartment was great - modern, comfortable and a great fit for a family. The balcony in particular is a spacious and comfortable spot to relax.
Thanks Magnar!
