The apartment is exactly as described and seen in the pictures. I found it very cozy and spacious, and the house is tastefully decorated. The living room is just great, and the kitchen is well-equipped (although a little small if you want to prepare a big meal).
The neighborhood is not the most trendy one in Stockholm, but there are plenty of good restaurants and pubs nearby. It is at the same time calm and very lively, and it is also within walking distance of many interesting places for anyone visiting the city.
Susann is a great host. She was always very keen to answer my questions during my stay. And since she lives next door it was very easy to get in touch. I highly recommend staying in this place for anyone coming to Stockholm.
