My colleague and I were travelling on business for a conference at the Bella Center, which was a short 10 min walk from Soren's apartment.
Soren was absolutely lovely and was very helpful in accommodating for anything we needed (including letting us check out later as our flight wasn't until that afternoon).
The apartment itself is amazing and extremely clean (he has very good taste).
Although not in the city centre, it's only a 10-15min metro journey if you did want to explore. Otherwise, Soren has lots of great suggestions of places to go and eat.
If you are thinking about visiting, I can't recommend staying here enough and will definitely try and book again when next travelling to Copenhagen :)
