Martin and Gung were away when we stayed but Martin's mum made us feel very welcome and we felt at home straight away. The flat is in a really central location, opposite a metro station and a two min walk to a tram and bus stop. There's loads of info on things to do in Oslo in the flat and bus/tram timetables making it really easy to decide what we were going to do and how to got there. The neighbourhood is lively with bars and shops close by. The flat was really clean and the room was very comfortable and being able to use the well-equipped kitchen was great to cut down on eating-out costs! Would definitely recommend staying here!
