Henning's apartment was a terrific place to stay in a great location in Oslo. Public transportation is very convenient both by tram and bus. Lots of nice places to eat within a short walk. The apartment itself is very stylish with a neat history. The amenities that Olaf has made available are great (kitchen, coffee/tea, speaker for music...). If you're there in cooler temperatures, the heated floor is a joy!
Henning was a wonderful host. He was easy to keep in communication with. Despite my transportation delays, he was super-accomodating regarding my arrival time. At the end of the day, it was pleasant to kick back and have a night cap conversation with him.
