Communication with Stine was smooth. Though we haven't met her during the arrival, her neighbor Rolf was there to meet us without delay.
Apartment was as per the description. Quiet and calm. Tiny but it has the essentials for the short stay in Stockholm. Just one note the apartment is at first floor level with access to the common terrace level, and since the curtain doesn't fully cover the entire door in the living/sleeping space, this can be awkward. Not an issue for us, since we found a solution to this.
Would recommend Stine's apartment to others.
