Thanks for the warning.
Can you identify the tower?
Traumatic/scary as the switch was can you describe her? Any sense she may have been passing trash and another girl will be along to the profile shortly?
Prescott House - just off Kennington Park.
She wasnt "horrific" but not attractive - slim, and in her 40's I'd say. As I left I noticed a, 50 year old asian woman walking in, so potentially a couple of them working there. I didnt go anywhere bar the corridor of the flat so my info is pretty slim pickings.
