Communal apartment sharing long term (Copenhagen)

I want to visit Copenhagen more often but cost of short term rental is high and availability is not reliable. I was thinking about renting an apartment with Protected content for a year or longer with other people who also wants to use it if they travel here often enough but not staying too long at a time, or maybe they do but would like to split the cost. There is something like that online, but Copenhagen is not on their list of locations. If anyone has any interest, let's discuss it further.
