One media-size room out of Copenhagen, cheap, quiet, clean and 6 mins walk to public transportation. S-train runs every 10 mins during the day, and 25 mins to CPH center. Big benefit is the good tourism advice from a crazy traveler...
Be aware : no kitchen for the guests !!! I don't normally accept long-term accommodation :(
The room size is like 12 m2 with big clothes cabinets and there is currently a queen size bed in the room. Only the guests sleep on the first floor with the bath room there.
Simple breakfast could be supplied by low cost.
I am from Beijing but live and work in Denmark as an electronics engineer. I have traveled a lot in Europe in the past 10 years. Recently I travel more outside Europe. I was in Japan and US last year. I love good food and like to see how local people live when I travel.
Now in my city, I have good tips for you if you want to travel more efficiently and try good food for a relatively lower cost. I wish you would have a good time in Denmark.
