It is a small apartment perfect for a lone traveler or a couple. You will quickly learn what hygge is as the apartment is extremely cozy and comfortable. It is up 3 flights of stairs so beware if you have a lot of luggage. Also the shower is small and will be a surprise to most, it does the trick tho... Just make sure to move the toilet paper first!
As far as location it is in a great spot walkable to several cafes and a little market as well as the main Copenhagen mall. It's a 5 minute walk from the dybbolsbro train station. I recommend getting a small city pass which is a better value than individual tickets. Between the S train and metro systems you won't need to rent a car. The host Karin was helpful and responsive to questions.
