Morton's apartment is wonderful. The apartment is stylishly decorated. All the amenities are of top quality. Check in process was easy, we messaged Morten our train arrival time and we messaged him again after the train arrived. They waited for us at the apartment.
The location of the apartment is about 10 minutes walk from the central station or from the opera house. It's right next to the harbor. So every time you go back or depart from the apartment, you are treated with the wonderful harbor view and would pass by the Oslo Opera house. It's definitely a nice way (or view)to start a day or wind down. (Currently there is some construction going on but with Google map you can still easily navigate to the apartment.
There is also a balcony in the apartment from which you can also get a partial view of the harbor.
The apartment complex is very quiet yet close to the city center. Also there are already 2 supermarkets and a number of nice restaurants within the apartment complex if you dont feel like walking to the town center for supplies or restaurants.
I would highly recommend anyone to stay here when visiting Oslo.
