We had a nice stay in Charlotte's flat. It is located right in front of Thorildsplan metro station in Kungsholmen. The apartment is well furnished. Charlotte is very sympathetic and arranging, we definitely had a nice contact with her. She accepted that we bring our cat with us and found a place to park our stroller downstairs, big thanks Charlotte !
Although our stay was nice in overall, I would just mention that the apartment is close to a trafficked road, which makes noise in the bedroom and the living room. No real problem to sleep with ear plugs though, but light sleepers might dislike it.
