Martin is the best host with whom I have ever stayed with so far. Even before the trip he was quite prompt in his replies. He offered to pick us up from the station and drove us to the apartment, showed us around the apartment and how things work, pointed out the various places we could visit and how we can go about doing it. Got to know us a little and we him. :) Overall, he was a great host and made us feel at home. The apartment was new, modern and a very comfortable place. I would definitely stay there again if I were to go to Oslo.
