I promise you, it is not rough! My entire family has lived there forever. I never had any bother living there, caught a direct bus to the RVI when I worked there in uni holidays.
My cousin teaches at the main primary, all her dc go there, my parents moved there to get me and my brother into the Catholic single sex schools which are great (another cousin is head at the boys) My family all live there.
Just buy to the right of the Catholic Church (church on your right). Left of Curtis Road is slightly more affordable but is less desirable, but my mum lives there, never had any bother. She has a very big 3 bed semi, garage, drive, 100ft garden. Never anything for sale in her street.
I wouldn’t live over the West Road, purely because the houses are smaller (except for Grainger Park Road) and there’s lots of ex-council/tiny back yard/no garden/very restricted parking and it is very busy/not as well kept, loads of chicken shops/taxi places. Streets are steep and leading down to a not brilliant area. Maybe this is the area people are thinking of: driving up from town on the West road, the area to the left isn’t brilliant. There is a massive amount of shops there, everything you could want, but not cafe culture!
It is a very community minded place, particularly for church people (my other cousin plays the organ and organises lots of events in the hall)
