Kerstin's apartment is in a superb location, easily walkable to many places and with great access to trains, buses, and taxis. There are many restaurants and supermarkets in the lovely residential neighborhood. It is about a 5 minute walk to the Stockholm Library, 20 minutes walk to central train station, and 30 minute walk to Gamla Stan. And about 30 minutes by taxi to the airport.
The apartment itself has a very spacious living room, kitchen, and balcony, with bedrooms on opposite sides of the floor. The kitchen in particular was excellent, with a large refrigerator, Nespresso machine, and many other great features. It was completely quiet at all times of night and day, and I had no difficulty sleeping. The bed was comfortable with a topper.
One thing to note if you have heavy luggage: the lift stops one floor below and you will walk up one flight. This was not a big problem. I'd be delighted to visit again!
