Susan's flat is LOVELY, in a wonderful part of the city -- quite close to many attractions, but quiet and so so green. The flat is really comfortable and spacious, although when we were there it definitely felt "lived in" insofar as Susan left most of here personal things in the apartment -- that can be a good or a bad thing depending on your preferences. Communication was a bit spotty at first, but improved once we switched to Whatsapp. Seems pricey at first, but it's actually a decent deal for Stockholm, especially for such a large, bright apartment.
Would stay again!
