We loved our stay at Johanna's place. It was clean and nice cozy size for a couple. It is so close to the subway and several grocery stores and many amazing restaurants and shops. Hornstull is a fantastic part of town! The view from her large window is just lovely, sit with some wine and cheese and watch the water! The park adjacent was also a great place to hang in the evening and people watch with wine :)
We also found the rest of södermalm very walkable from here, along the water or through the center, it's just filled with interesting neighborhoods.
Would definitely stay here again in return visits!
