We staid one night at Kristina and Anna's place. Despite the fasct we did not meet Kristina, we have been welcomed by Anna in the apartment. She was really helpful, easy to communicate and kind, she gave also somme advices to find a place to eat. We had a great time in the apartment. Its's close to the city center with a great view on a kind of à canal.
Apparently we were the first Airbnb guest at Kristina and Anna's place, but I totally recommande this place for your stay in Copenhague.
