Hi Sophie
I live just outside of Houston. I'm not familiar with Aldine-Westfield Stables, since it's not near me, but it looks good from the website. Actually, it might be about as close as where I board now, just in the other direction!
I also run a website called
HoustonHorses.net which has listings of many boarding stables, as well as other horse-related facilities and businesses - vets, tack shops, feed stores etc. in the Houston area.
