The location of this apartment is perfect. It's easy to get to everything from here. If you prefer to use taxis, download the taxa app and use it - taxis will come within minutes!
The apartment is not huge, but we were 3 people and the size was perfect (we spent most time out exploring). Some folks talked about the front room being loud. There was maybe one night that the street was loud (after a soccer game in the city), but it was not something that would preclude me from staying here. You just have to know that sometimes there will be revelers outside.
There is a little convenience store at the end of the street so you can pick up items like water or snacks. And of course, being in Nyhavn, there are many MANY restaurants right there. (Of course, some of the best restaurants in the world are in Copenhagen, so be sure to explore beyond the area).
We were able to leave our luggage at one of Edward's restaurants when we arrived before check-in. Edward and his team are not the most communicative hosts, but we got the info we needed when we needed it!
The place was clean and comfy, and I would definitely stay there again.
