I live in Mossley Hill at the moment and there are not many Poles here (too upmarket), but lots of Poles in Tuebrook, Old Swan, and Wavertree. I'm a postman, until July anyway, and I've delivered to lots of Poles in those areas. You meet lots of people as a postie, and you get to know the makeup of different areas, especially as I essentially cover for other posties in most parts of the city.
I had to use google earth to Mossley Hill.

I live in Waterloo.
