It was very nice and easy staying at Astrids place. She provided us with all necessary and helpful information about her flat and things to do in Oslo before and during our stay there. The flat is very pretty and clean, you have a nice view over Oslo from the balcony. It takes around 15 minutes to walk from the Central Station or a few minutes with the Tram. I can totally recommend to stay at Astrids place.
