So Glasgow's great, not desolate and depressing?
A ha.
Port Glasgow is about 22 miles up the road. But that's going up in the world too. You can still get an apartment there for about $5,000 if you shop around all the same.
But yes there are bits of Glasgow too that are fooking horrible, mainly the outskirts where slum dwellers were sent to newly built estates for a supposedly better life. But there's lots of elegance and green spaces too.
I thought you meant Glasgow when you said Port Glasgow. I didn't realise they are separate places. This is paraphrased from wikipedia.
