Lovely place well situated in Copenhagen ! The apartment itself is awesome, decorated with taste and has anything you may need during your holidays. They even let you use their bikes. The neighbourhood is nice too, there is a safe playground at the end of the street, a big park at 10min walk, 2 supermarkets open everyday at 100m, and a cafe/bakery at 300m (which sells excellent cinnamon breads !). You can definitely let your car parked during your holidays and bike around. City center is 15 min away by bus or by bike (maybe 10 min if you ride your bike fast, but we were with kids...).
Mette and Steen are very flexible about departure and arrival time, and we were nicely welcomed by their daughter. They are not intrusive during your stay but they will answer rapidly any question you may have.
In a word, we can only recommend you this place !
