We spent four days in The Pink House and enjoyed everyone of them. The apartment is spacious, light, and very tastefully decorated. We especially enjoyed the large kitchen table, where all six of us (four adults and two children) had plenty of space for joint breakfasts and dinners, and board games in the evenings. Outside, there is a small garden with a table and chairs, and (to the joy of our children) a trampoline.
The location is really good. It is a quiet neighborhood, and at the same time just a short stroll to the city center. It is also close to the river Akerselva with its nice trails and Grünerløkka with a number of good restaurants and bars. If you come by car, there is parking space just outside the house.
Communication with the owner was first class. Always quick and very helpful. We missed some kitchen utensils when cooking dinner, and a few hooks to hang our clothes, but we managed.
The Pink House was a perfect place for our stay in Oslo, and would love to come back another time.
