Anton is a great host: easy to communicate, responsive, takes care of the needs/questions, provides all necessities, flexible with check-in/check-out.
Apartment has full kitchen. Living room is spacious. Beds were very comfortable for us. However, only one bedroom had free closet - the other one was full of owner's stuff.
The location of the place is awesome: close (walking distance within minutes) to train, close to many restaurants (one restaurant is in the same building) and places for a breakfast, very convenient walking to many attractions. Have had to use public transportation only to go to CopenHill and Reffen.
We were there in the end of August when streets were full of people and party buses were running all day long. You have to choose either accept the street noise with windows open or deal with the hot conditions inside with windows closed - there is no air conditioner in the apartment. Even if the windows are open but room door is closed - there is no relieve in air movements. Most likely it is not a problem in late fall, winter, and early spring.
Bathroom was a challenge: floor needs to be cleaned by small hand squeegee after shower as you need to walk through the shower to the toilet or to the sink. In hot summer - you might think of another shower after cleaning the floor.
