avoid langney/shinewater/willingdon trees, maybe look out for meads/old town as desired areas. town centre is half decent and half awful - avoid particularly the langney road and pevensey road areas (unless you love crack, cheap lager and being harassed) but around upperton is very nice - large victorian conversions, loads of room, nice parks around as well.
eastbourne can be a pricey place to live but is bloody lovely, especially in the summer!
Pretty similar what a ex flatmate of mine said that lives in Eastbourne after moving from Crawley 3 years ago. He loves it there.
