My friend and I had a fantastic stay in this apartment. The apartment is perfectly located, esp. if you are in the mood for good food (Nytorget 6, Urban Deli, Shanti Gossip, A.H. Glassbar, were our faves) and good shopping (Acne Studios, Grandpa, La Bruket, and tons of vintage stores). If you're in for nightlife, you're in the right neighborhood already. Going outside the neighborhood? You're in luck. There are A LOT of bus stops that run through the neighborhood that can get you anywhere in Stockholm in a reasonable amount of time and it's a short walk to the T Bana.
The apartment itself is gorgeous. Lots of sunlight, and it overlooks a park! Bjorn provided everything that we needed (we made some big breakfasts while we were in Stockholm) and he was super communicative and flexible.
I will definitely book if I visit Stockholm again.
