We were staying in Karin's apartment for a week in August.
It was an amazing experience.
The apartment perfectly accommodates three adults, is very spacious, modern and stylish. There is so much light in the rooms and there is a beautiful terrace, which faces the park.
The apartment had everything we needed, all the kitchen and house utensils, there are two bathrooms and the main room is even more spacious than on the pictures.
The terrace is an amazing place to start a day or to relax in the evening, it has a great view, is decorated with plants and there are several sweet spots to enjoy your time.
The area is excellent: there are dozens of restaurants for different tastes nearby, we visited one or two a day and they all were good. English menus are a rare thing and but everybody speaks English fluently and we had no problems.
The park in front of the house is wonderful, especially if you have a kid (there is an enormous playground) or want to play football (there is a field, lit with light in the night)
The river is 10 minutes by foot and the opposite embankment provides amazing views of the city, it is also a lovely place to stroll to or from the city center or have a morning/evening run. There are quiet parks nearby, Stockholm has parks everywhere, so don't hesitate to walk in any direction and just explore the city.
There are several supermarkets nearby, the tube and bus stops are just at the corners of the park.
The house is easily accessible by Flygbussarna if you travel to or from Arlanda, there is a bus stop in just 5 minutes walk.
Karin was a good host, we have no organizational problems at all.
I can highly recommend Karin as a host and the apartment as a wonderful place to stay during your visit. We enjoyed Stockholm a lot and the apartment played its part in our positive experience.
