Martin was a wonderful host even going to the trouble of collecting us from the railway station and dropping us off to take delivery of our hire car. He provided us with a lot of info and there were brochures on Oslo's attractions in several languages. His apartment has everything needed to make your stay comfortable and enjoyable. It's is about 30mt from the bus which runs every 15 mins and around 10 mins ride to the station and city centre. There's a supermarket about 8-10 mins walk away together with restaurants. We would wholeheartedly recommend his apartment to anyone coming to Oslo. There is also a nice outdoor area with a table and chairs.
