Lena's apartment is amazing. We had a really great time in Copenhagen, and Lena's apartment had a lot to do with it. The apartment is very well located, in probably one of the best areas of the city (Nørrebo). It is very quite, very close to many good restaurants and nice shops, and quite close from the city center.
The apartment is also very cozy and it was very clean. Lena was also very nice and attentive, and always reachable.
I would not hesitate to stay again in Lena's if I ever come back to Copenhagen.
