This listing had many positives and a few things that were not so positive. We found the space to be quite agreeable with an extremely comfortable bed. The location was perfect - bakeries, chocolate store and supermarket within a few blocks. It took us 10-15 minutes to walk to Nyhavn. The owners were very responsive when we locked ourselves out, solving the problem within minutes.
Please take the issue of five flights of stairs seriously. We didn't mind, but if you are not fit or mobile this is not for you. However, the view is spectacular and the neighborhood quiet ( as is most of the city).
The downsides were not significant, but do make the apartment less than expected. When we arrived two of the bedrooms had no lights and the dining table also was in the dark. Cheryl, the owner, responded the next day with table lamps set on the floor and on chairs. Lighting solved, but actual floor lamps and/or tables would have made the space look better. In fact, the apartment while quite nice was a bit "rough around the edges" appearing more like a young adult space than not. Lastly I think that small issues ( which I communicated to the owners directly) such as paper towels and filters for the coffee machine would have made a nicer touch..
Given the above, the listing was OK for our purposes this time but not for another visit.
