Tried yi an some time ago.
Location is at the backside of the famous Mt S so not that convenient. But it's pretty secluded so that's a plus point.
Looks wise is very much a milf so don really gam me. Body slightly bah bah but still OK. boobies quite big probably a C although feels man made.
Sensual wise very service oriented but no chemistry with her. Somehow everytime she lick me she will use a tissue to wipe my body. It sort of disrupt the momentum I feel. Overall I would say service wise she is good but not really my cup of tea.
