I chose this for a longer-than-originally-planned stay, and it is a wonderful place! A few of the highlights -
* the free laundry (and laundry soap, and dryers) are excellent;
* the luggage storage came in really handy!
* the location is really just perfect for exploring Copenhagen; I could walk to pretty much everything within 20 minutes, and it's right next to a Metro station too;
* lots of great food places nearby;
* handy little kitchen
It doesn't have air conditioning but that really didn't matter; even during the hottest of days I could just close the window and things stayed reasonably cool, and there was a fan that worked quite well.
I'll be back!
