The apartment is just perfect for a couple, the spaces are well optimized and has the plus of a balcony with a nice view. The location is very quiet and also very well connected, with the metro wich will take you in Gamla Stan in 5 minutes.
Annika is an excellent host, always very caring and available. She also gave us very good tips about some places to see around the city, which we enjoyed a lot.
Definitely a very good choice if you want to spend some days in Stockholm.
