Hi, I grew up in Taunton and have lots of freinds and family still there. We moved away around 5 yrs ago to London, then Hants but still visit Taunton very frequently.
Good/bad areas.... TBH there are no terribly bad areas. Halcon/Lyngford are the only really bad ones, but they are predominantly council areas. There are lots of lovely villages just outside of Taunton.. Kingston St Mary, Cheddon Fitzpaine, Ruishton, to name a few.
The town centre is very good. It's changed quite a bit even in the 5 yrs since we left. It has all the leading shops and lots of variety.
Schools, well DS1 was at North Town School and it was brilliant! I'm not very in touch with other schools, but do know there aren't many really bad schools. My best freinds daughters go to Cheddon Fitzpaine school and she is happy with it. My nephews go to Cotford St Luke School, but actually I have to say my sister isn't that happy with the school.
Ooh nursery schools/playgroups...DS1 went to Albys, which was and still is very good. Same lady running it, so it can't have changed that much.
Anyway, I could go on and on. Basically Taunton is a nice place to live, friendly enough, I think you will be very happy there. HTH
