We had a really nice stay at Trine's house. We had a little trouble with our flights and arrived two days late, but Trine kept us well informed and once we finally reached the impressive house with a beautiful view over the sea the trouble with the flight and the lost baggage was almost forgotten and the vacation started :-)
Public transaportation to the city is rather easy and the small Joker supermarket at the train station has all you need for the daily life and was very helpful.
Thanks for having us in your house and we can only recommend it to everybody who wants to enjoy vacation in Oslo.
