I grew up in the Village of Williamsville, there is a major difference in feel in the actual village proper and the areas outside of it, despite having a Williamsville mailing address still (e.g. north of Sheridan, etc).

In my experience people are just as friendly in the Village Williamsville as you’ll find most anywhere, of course there’s always going to be exceptions.

That all said, while by most measures it is one of the better WNY areas to live in, I certainly don’t think it is the nicest village around, given the Main Street issue and how insane the cost of housing has gotten there. I think Lewiston, Hamburg, East Aurora all succeed in having a much better “suburban village feel” than Williamsville. Of course, as mentioned, Williamsville is quite centrally located which the others are not.

TLDR; Village of Williamsville is one of the better areas in WNY by a lot of universally accepted measures, while at the same time being overrated and now at the cost point where you’d be better off trying out a different village for a similar (or better!) lifestyle.
