Mancheser is a realtively small place.
Are you able to travel around Manchester or does it specifically have to be M12 walking distance.
I ask since your request and thread title is centered around "M12 area"
Honestly I'd have to rack my brain to know if a girl was walking distance for that postcode area
BUT
As for recommendations generally in Manchester I could fire them off for you with less thought and effort.
Also when more specifically will you be there since that will affect availabilty of recommendationds.
