I had my parents stay at Valentina's apartment for a week and it was really great.
The rooms are large and the balcony makes it a really cozy place to begin or end your day.
And the best thing is that is located in my favorite neighborhood, Vesterbro. It is only 10 minutes walking distance from Central Station and even less from other bus, metro, suburban train stations.
Valentina was really nice and easy to communicate with.
Totally recommend it if you choose Copenhagen as your next destination!
