Matthias' listing was the perfect place to stay at for our quick trip to Copenhagen. My friend and I both found the neighbourhood very safe and the apartment was in a perfect location. Not too noisy and still close to the city centre. There is a gym right across the street and the most perfect pizza place just downstairs (you need to check it out if you book - the pizza is amazing and the people speak many different languages and are so kind). The view from the kitchen of this bnb is also beautiful. I would suggest requesting some more photos of the bathroom to get a feel for the lay out of traditional Copenhagen bathrooms if you've never been!
