We stayed in this apartment in July. It was quite nice, the check-in and -out was easy, the communication with the host was unproblematic. The beds were more or less comfortable, if you are a group of five, one of you will have to sleep in the living room. The whole apartment is pretty small, but there is enough light and space. The bathroom, as well as the shower is very small.
When we stayed there, the shower had only boiling hot water, when you tried to open the valve farther than a bit.
When we told the host about this problem, they were very keen to help and reacted quickly. They sent a handyman, who was also very fast, we actually missed him. But the shower was only slightly cooler after.
If you are sensitive to noise, I would not recommend staying in this apartment. You can hear the people from the street all day and especially over the weekend you'll hear drunk people until 5am. If you have a light sleep you will not be able to sleep.
But the partement is located, right in central Copenhagen, there is access to the metro and some important attractions. It was good for our interests, but we really did not get a good nights sleep.
