We stayed in Soeren's apartment as a family of 3 for 2 nights and loved it.
Location wise it is perfect, in a quiet residential area, but close another to shops/restaurants and most importantly Nordhavn station which gives you cheap and frequent access to most parts of Copenhagen.
The apartment itself is decorated in a unique way which catches your eye and was extremely comfortable for our stay, it felt like home for the time were we there (although make sure you're fit as there is over 70 stairs to get to it).
Soeren was very accommodating, communication was easy and we had no problem collecting the keys and checking out with him.
If visiting Copenhagen again I would definitely ask Soeren if I could stay again.
