Heron Reserve is pretty close to me. It's a good location in West Ashley, very close to I-526 and also Hwy 17, both of those are major roads in the Charleston area. You're also really close to Walmart, Citadel mall, Costco, some restaurants, movie theatres, etc.
We didn't personally look at those apartments when we were looking to move down, but I drive by them often (they are right off Glenn McConnell Parkway which is a major road here). They are really nice looking.
Glenn McConnell can get kinda backed up in the mornings near West Ashley High School, but I think being at Heron Reserve, you're kinda past the morning backup so you should be good
