Karen was a perfect host. She had camomile out for me when I got there. She is also seems very knowledgeable about the arts and classical music. Also there were interesting medical drawings in the hallway which makes me think she is in some way related to the medical profession. Or, naturally curious.
Unfortunately I was on a tight lay-over and didn't have the time to ask her so many questions.
I would definitely go back for a much long stay at her incredible flat.
