Really enjoyed our stay at Nivi's, she was always very quick to respond, let us leave our luggage in the flat on the last day, and check in was seamless (Nivi met us late Thursday night after our flight). The best part of the flat though is the location - people kept telling us we were staying on "the coolest street in Copenhagen" and definitely seemed to be true! It is right by the meat packing district so there are so many great restaurants, bars etc (and greenery and parks!) right on our doorstep. Despite this the flat was not at all loud, and everything was really comfortable and spacious - strongly recommend!
