Mari´s apartment is very well situated (500 metres from Central Station) and at a walking distance from the city centre and many points of interest. It´s small but has everything one person or a couple might need. It is well equipped. Mari is an Oslo guide so she gave me information and also invited me to one of her guided tours. She has prepared a very complete folder with tips about the neighbourhood, useful information and the history of Norway and Oslo. I really enjoyed my stay.
