Everything was just excellent! The apartment is very new and very beautiful, provides plenty of space for two, is very well equipped, and is located in the most modern and central part of Oslo, at the waterfront. As the houses at Tjuvholmen are very new, there still is some construction going in, so there is a little noise on weekdays, but it is not much more than you would expect in the city centre anyway.
The communication with Nils was always very good and he responded very quickly and engaging. Nils had prepared everything for us at best. We will surely consider to rent this apartment again when we come back to Oslo.
