Lived at the Boulders for about a month now. As a New Jersey (by away of Boston, by way of Plano) transplant, I'm pleased with the quality of the homes and the attentiveness of the staff. I haven't noticed any noise or other community issues. Also, living on the Iron Horse is pretty sweet, and it's distance to either BART station is appreciated.
Oh yeah, and the parking is fine. The spots are normal size and covered, and even though ours is in between two support beams, it's very easy to get in and out of. Since our unit faces Civic, we usually park on the street no problem.
