Westbury Court is a very nice estate. I don't live there but have friends who did live there up to last year. It is an estate that has matured nicely over the years, is well kept, and is largely owner-occupied, as far as I know.
I would consider the location good, it is, as you have said, w/in walking distance to the shops, schools and village. It is also very convenient for the bus to town. The local primary schools have a good reputation. I am not aware of any negative impact in relation to Adamstown. Very best of luck with whatever you decide.
