Karin's apartment is really a very nice place. The location is ultra cool in a kind of museum, in a golden house on the top floor, with a splendid view on the nice park behind the building. The apartment is equipped with everything you need. Different foodstores are very close, two metro stations and differend bus stations are just a few minutes away. The Flygbussarna Airport Bus for Arlanda has a stop just 200-300m away from the apartment.
Dealing with Karin via Text was very uncomplicated and easy. She left a handwritten map, so you'll find all the locations (stores, public transport, etc.) at first try.
Our family (2 adults, with 2 boys 15 and 17) enjoyed our stay (one week) in Stockholm very much. We would recommend Karin's apartment to everyone visiting Stockholm.
