Seriously, I suggest someone (+bring friend for security) in Stockholm area, go to their home and ring the doorbell, perhaps that would help verify two things.
1. That they are who they claim to be, and that it's not just the address of some old lady with dementia.
2. You can ask them outright, what's the current "status".
I would happily go with Rix and check the situation out.
I just want to make sure they actually live there first, so we do not go and know on someone randoms door xD
