Marianne is an excellent host.
She is very friendly and attentive and excellent communicator. Her directions to the apartment were easy to follow and she greeted us with a big smile.
Her apartment is sparkling clean and cosy with some really fine personal touches in the decoration. It is only a few minutes walk from tram and bus stops or a very easy 20-30 minute walk to Oslo's centre if you enjoy exploring the city on foot.
I highly recommend both Marianne and her apartment for anyone visiting Oslo for a trip.
