The appartment is on the island Malmøya, so a quiet and beautifull location, but not in town. But it is only a little (12 mn) walk to the bus station 85 to Oslo Sentralstation, and then 15 mn with the bus. There is a direct bus every hour, and another one via Ulmøya. The busses are very exact, and drives every day, also by much snow :-).
The house contains everything you may need and is pefect for one person, or two.
I didn't meet Linn, but the communication with her was easy and friendly.
I recommand, if you don't absolutely want to stay in town.
