The apartment was lovely and in a great spot in the city, which was reasonably still and quiet at night, it was clean and bright and lovely. I love Copenhagen.
BUT... the wood floors are very hollow in this building and we were unfortunately under a loud family with no care for anyone around them with very, very active children who jumped off couches, dragged furniture across floors, threw things, screamed, yelled, and parents that stomped around very loudly. It went on for hours and hours whenever we were in the apartment. Because it was warm all of the windows were open - there is no air-conditioning in the apartments - so you could hear everything echoing through the courtyard on top of the constant banging. Even with the windows closed it was loud. If the noisy guests weren't in the apartment the children were in the paved courtyard running around screaming which echoed through the whole building (I'm sure we weren't the only ones who mentioned the noise).
We were working for part of our week-long stay here which was disrupted due to the noise and let the apartment hosts know of the upstairs commotion who said they checked on the family, but couldn't do anything to move us as they were booked out. We felt pretty trapped to be honest, I'm very accomodating to others and a well seasoned traveller so you learn to put up with a lot! But this wasn't a nice experience at all, not being able to cancel without losing money, or move to a different apartment, it really impacted our trip and our capacity to take meetings and work.
I'm aware you cant control children or loud families so if you do stay here, I suggest requesting an apartment on the top floor to avoid the vibrational torment of hollow floors and take earplugs, because there will always be people who don't know how to share an apartment building. And be prepared to become intimate with the sounds of your neighbours if the weather is warm. Apart from that, the apartments are nice!
Also there is no elevator and only stairs.
