Astrid's place is a big 5 bedroom house, about 20 minutes from central CPH, and about 25 min from the airport by bus. Very well communicated by public transport or even walking. There is a supermarket within 5 minute walking distance.
The house is quite big and comfortable, we were there in the middle of winter and it was always very warm. The kitchen is very well equipped, with everything you might need and then some.
The check in/out was very easy. Contacting with Astrid was always quick and she was very helpful. I would definitely stay with her again!
