Nana really is a cool and welcoming host. We really liked her cozy apartment, located in a very cool neighborhood (coolest in the world, according to some magazines). The description is accurate, you get exactly what Nana described: a cozy bedroom and access to the bathroom. There is also some tea and water in the room, but no access to the kitchen/living room. For us, this was fine, since we only spent 2 days in Copenhagen. Also, as mentioned in the description, the bed is pretty small (120cm). For us it was just enough, nothing to complain about.
I strongly recommend you rent a bike because Copenhagen is one of the most bike-friendly cities in the world. There are a lot of bike rentals nearby. If lost or unprepared, Nana can help you with ideas and suggestions. Enjoy!
