The apartment is located near a metro station and a train station. The metro station is for the M3, which goes around the city in a circle, which is very convenient. The host responds fast and is very eager to help. We knew the apartment wasn't "well-suited" for a family with a small child (there are "destructibles" everywhere on ground level, so we had to watch the little one like a hawk), but since we were out sight-seeing most of the day, that wasn't a big problem. It's great that we could have the entire place to ourselves for an affordable price.
All-in-all we had a great stay. I would definitely recommend this listing for a visit to Copenhagen.
