I enjoyed my stay in Fredrik's apartment. Björkhagen is a nice area to live in, it's very quite and green. It takes about 10min to get to the city centre by metro (the subway system itself is very convenient in Stockholm). The apartment has all the essential things, which you might need during your stay.
Fredrik is a kind and caring person. He can give you a good advice based on some random thoughts on what to do in Stockholm. I felt myself secure in his apartment.
so i would recommend it to everyone, who's looking for a place to stay in stockholm. and thank you, Fredrik, for your hospitality.
