This is place is fantastic. It's located right next to the vibrant area of Cristiania, you can get to Copenhagen Street Food in a few minutes of walk and the metro (Christianshavn) station is also only a few minutes away.
Esser was very flexible with the check-in time and responded very quickly to any of my questions.
The flat is awesome: it had everything I needed and has a very cozy and modern atmosphere. It's perfect if you travel as a couple or alone and would like to have the typical Scandinavian experience.
