Shirley's airbnb is a good hour's walk from the center but is very easy to reach via train, bus and metro. Public transport is well organized in Copenhagen. It is a beautiful apartment and everything you need is there whether you want to cook, do the laundry or just relax from all that walking. There is a shopping center nearby with bakeries and a large supermarket. The house was neat but I did not find the shower very pleasant. Definitely recommended to stay there.
