Karin's apartment is perfect for exploring Copenhagen. It is in a lovely part of town a short walk from the central station. There are some cafes and small shops nearby and the more main shopping streets are a few blocks away.
The apartment itself was perfect for me and my girlfriend. The bed was comfortable, the apartment light and airy, and the decor very tasteful. It is definitely suited to just two sharing.
Karin as a host was excellent - she was available online for any queries and the place was left in an excellent condition.
In summary, my advice would be if you are a couple looking for somewhere to stay in Copenhagen and this place is available - book it now!
