I really loved my stay at NORD. The flats are very comfortable, well located (two metro stops to Christianshavn), with supermarkets at 2 min walk. One must be ready to maybe have people passing and stairing from the front through the big glass windows and doors if you are on the ground floor, but you can always close the curtains.
There are some little things which can improve the stay of long time travellers, I personnaly was there 6 weeks (but maybe irrelevant for shorter stays): in the Kitchen there are many plates, glasses that is fantastic but the cooking tools is quite poor, there was not a basic big cooking spoon (just a spatula) I had to buy on, not a real strainer. Their is a oven but which metal sheets could not stand straight, and actually no kitchen containers (molds or others) which can go inside this oven (so how to cook things in it?), a Microwave would be nice too and there is the place for it above the oven. The pressure of the shower is a bit low.
But Beside that (which for non-cooks or shortstays will not be a problem) the flat is so confortable it was a real joy to come back "home" after work!! I rarely felt that confortable taking an Airbnb abroad! I recommend it!
