Birthe was too kind and helpful. Her apartment is quite nice, spacious and cozy. Around it there are several restaurant (Thai, Italian, kebab, ...), a good supermarket, two splendid bakery and so on. The bus stop is two minutes away (walking slowly) and the trip by bus up to the center is about 10 minutes. The metro station is only five minutes walking and the line is direct to the airport. The neighborhood is calmly.
In future trips to Copenhagen we will stay in Birthe's apartment again.
