I've seen Leggy Kelly twice.
Location is a really really seedy block on the Edgware Road just north of Marylebone Road. The flat itself is nice but the walk up to her floor is like something out of a 1970's Kojak episode in some tenement block. There are little mouse traps on each landing (no, really!).
She is very slim and shapely. Teeth look a bit mangy but she was clean and fresh. Nice personality and polite. Service was OK, nothing memorable about it frankly. OWO and 69.
She was good enough that I saw her a second time but just as i came out of the shower she told me that her landlord was on his way and that I had to leave - unless I wanted to do a 15 minute booking instead. I declined.
Won't be seeing her again, and that's a fact.
