Arne's apartment is just as described in his listing. The Supermarket downstairs proved to be very useful and handy.
We arrived later than expected due to problems with the train - smoke in the Airport terminal and tunnel, but once we were able to board the train, getting to Arne's apartment by following his directions was easy.
Between our sightseeing plans and Arne's work and work-out schedule, we didn't see much of him, but he did review all of the features of the apartment.
