Finding an apartment in Copenhagen can be competitive, but there are various options available to make the process easier. Try joining housing-related groups on Facebook such as “Leje i København - Rooms for Rent in Copenhagen” (facebook.com/groups/roomsrentcopenhagen/). Popular rental portals where landlords and agents list properties available for rent in Copenhagen include Bolig Portal (boligportal.dk), Leje Bolig (en.lejebolig.dk) and Find Bolig (findboliger.dk). However, keep in mind that the competition can be fierce, and it might take time to find the right place. 

Engaging a real estate agent can be beneficial, especially for those who prefer professional assistance and personalized service. This may involve additional fees or commissions, but real estate agents have access to a broader network of rental properties and will guide you through the rental process, negotiate on your behalf and handle the paperwork, making the experience less stressful.
