Clean stalls, no ammonia smells, prefer 14X14 or 16X16 for stall size if the horses are in for any length of time and I'd pay extra for size, heated barn. A covered or heated indoor arena (depending on where the barn is) and a couple of outdoors. Trails, miles and miles of trails. Personal Tack room a MUST, not shared with anyone, tired of supplying the entire barn with fly spray only to find I never have any for MY horses.
I'm spoiled now, I have my horse at a show barn and never have to tack up, groom or do anything but ride, so ......Hot & Cold Running Barn Help would be lovely.
Large turn outs a must, not shared with other horses.
