Lukas' and Julija's space is modern, open and really pretty. The room I stayed in is right next to the living- and the bathroom. This allows you to use their beautiful rooms, or to just stay private to yourself, if you like less interaction. They both gave me a tour of their apartment and told me tipps for what to do in Copenhagen. They are really great hosts and their coffee is amazing. ;)
The flat is located near the university in a newly built part of town. It is close to train- and bus-stations, but in Copenhagen what you really want to do is travel by bike. Right next to the flat you can find two "Donkey"-bike rental stations and you are perfectly connected to the fantastic bike system of Copenhagen.
I was super happy that I found Lukas' and Julija's flat and would recommend it to anyone who is looking for a modern and well connected place to stay at.
