The location could not have been better no matter what your reason for visiting Copenhagen was. Close to good restaurants.
Close to railway. Quiet family oriented neighbourhood. There are a few things as regards in apartment ammenities that could have been improved on such as bed sheets etc. But we are not regular AirB&B users so it would be unfair to be over critical of such matters. My wife and I would recommend Tanja as an AirB&B Host.
