I had a very good stay in Line's apartment. The bedroom really is huge, with a comfortable armchair and sofa and a really comfortable bed. Line is friendly, helpful and welcoming. It was nice to be able to prepare my own meals in the kitchen if I wanted to.
The location is very nice and it's just a short walk to Vigeland Park. It's only a few tram stops into the centre of Oslo, public transport is efficient and easy to use.
Altogether I would rate this place highly in terms of comfort, space, convenience and location.
