We stayed for 4 days in the apartment and we can only say it was the perfect place !
The location near the station and the Opera are great, subway and tram only few steps away. So everything is really easy to reach.
The apartment itself is in the old Posthallen, which is a nice thing and the space is generous with lots of light and a big void (duplex space).
All features are present in the apartment.
Further on was the communication direct and very friendly, so we can only recommend Rune and his place.
We would certainly go back !
