The apartment is nice, the location is very convenient, and communication with the host is excellent. It's everything you need for a great stay in Stockholm.
It's right next to Slussen subway station, making it easy to get to Central Station and anywhere in the Stockholm area. You can also easily walk to old town Gamla Stan. Even if you stay in the neighborhood, Sodermalm is a very trendy place with plenty of shopping and great restaurants.
Katarina was always quick to reply whenever I had questions. We relied on the internet for planning our days. When we had trouble with the wi-fi, I messaged her and immediately got an answer with suggestions that fixed our problem.
I would definitely recommend this apartment to anyone visiting Stockholm!
