I apologize in advance if this is a long-winded response.
I was born and raised here in South Irving. In fact, I will be buying my parent's house. I can't wait. I live 10 minutes from Texas Stadium (rip), and 10 minutes from Cowboys Stadium in Arlington. South Irving is a twilight zone, but I love it. Michael Huff is from south Irving, and he went to my high school. He was a couple years younger than I.
Look at apartments off 635 and MacArthur. There are a myriad of nice apartments along MacArthur starting north of 114. Valley Ranch is just north of 635. My friend used to live in apartments right across the street from the practice facility that collapsed, and those were nice. There is a pretty big Indian population in that area, which has always baffled me. There are tons of nice little shops, and eateries.
Avoid 114/121 near the airport at all costs when driving. THE WORST TRAFFIC EVER, and on top of all that, construction.
Don't ever go to the Irving Mall. Like ever.
Anything else you want to know, feel free to shoot me a PM.
