I spent a month in Norway, using Carl Andreas's wonderful place as my base as I did research in Oslo and elsewhere. I have never enjoyed an Airbnb more. It's in a cool neighborhood where it was fun to walk around or go to one of the restaurants nearby; not far from Vigeland Park where I ran; on a metro line that got me just about anywhere; and an easy walk down to the harbor. The place itself was a delight, with a little balcony overlooking much of the city. And whenever I had a question (and I had many for Carl), he responded instantly. Plus this place is in Oslo, which blew me away.
