We stayed at Martin's place over the weekend on the 9 Novmber and he was a great host.Directions to find the apartment were not hard to follow, although there was a bit of confusion in the beginning as apartment number was not updated on the website. The apartment itself is very clean, exactly like the pictures and very well insulated. His place is central to a lot of attractions and public transport. Martin himself gave us great recommendations on what to see and how to get there. He even pointed out to us a great Vietnamese resturaunt around the corner from his place when we mentioned how we can't find a decent pho resturant in London. We would definitely recommend staying at Martin's place and would not hesitate to come back if we were in Oslo again.
