My family stayed in this flat for 10 days over Christmas and Jonas's apartment did not disappoint! It's spacious, modern, stylish, comfortable, clean - a place you can enjoy spending time in. I would recommend it to anyone and definitely try to stay there again if we go back.
Jonas was a very nice host who answered all my questions about the booking promptly in excellent English and made us feel welcome and at home. The wifi is very good, there are big windows, a nice balcony, comfy sofa, and nice big rustic table to eat on if you plan on cooking a bit. Nice big bathroom too with a washing machine and there was a drying rack we could use. The flat was also warm so we barely had to turn the heating on. Beds were comfy with fluffy Scandinavian duvets.
The immediate area didn't seem have much going on (though this could be because we were there at Christmas time!) but the train station was just a couple minutes walk away with central Copenhagen 10-15min on train. Very easy and convenient.
There is also a good supermarket right by the station and a few more in the area you could walk or drive to. We came by car, so were a bit concerned about finding overnight parking on the main road 200m away but it was no problem at all. (Just fyi, it was all parallel parking spaces)
A lot of the reviews mentioned noise from the trains but we did not find this a problem - the sound insulation was good when the windows were closed. Jonas left disposable ear plugs to use though which was very considerate.
Beds: The flat is comfortable for 4 people though an extra person could easily sleep on the sofa I imagine. There is one standard double bed in the room behind the TV. The room behind the kitchen has two single beds and overlooks an inner courtyard so absolutely no train noise here. Both rooms have black out curtains. (A picture in the description shows bunk beds but these have been replaced with the normal singles).
Just two things to note -
There was not any closet space to use so be prepared to live out of your suitcase. While there was a coat rack area by the door for shoes/outerwear, there wasn't anywhere really to hang clothes in the bedrooms - no wall hooks or coat racks.
The overall lighting was very nice and stylish, but not all the beds had convenient reading lights/bedside lighting so if this is important to you, you might want to bring a travel reading light.
Fantastic apartment overall very accessible to central Copenhagen.
