I had a really good three night stay with Kathrine. The apartment is in the basement of her house. It's compact, but well equipped and perfect for one person. It has a single bunk bed which could present a problem for someone who has problems with managing a fairly steep ladder but I found it fine. Transport links into central Oslo are good and the area is quite hilly with some glimpses of the Oslo Fjord. It took 20 minutes to get into Oslo Central Station from the closest T-Bane station. Kathrine was welcoming and very helpful and was available to help me out when I needed her. The nearest supermarket is about a 7 minute walk away and is open long hours. I can recommend this nice, convenient place to stay.
