Steffen's apartment is a great place to stay in Copenhagen. It is clean, bright, airy, and very very quiet. You'll be in a cozy building with a nice inner courtyard. People have dinner on their balconies and kids play in the courtyard, but no one gets noisy. The best part is the balcony, which has tons of space, a comfortable outdoor couch, a heating lamp for cool nights, and even a small grill. The living room, kitchen, bedroom, and bathroom are all comfortable and well equipped too.
The location is great as well. Half a block away there is a supermarket, and another one 2 blocks away. There is an amazing bakery and a few takeout places right on the block. Around the block is a great small coffee place as well. And despite being in such a quiet spot, you'll never really need a taxi or even the nearby metro station; Tivoli, Stroget, Fisketorvet Mall, and most tour pick up locations are less than 15-20 minutes walking distance.
