I have been a resident here for the last 3 years and hopefully my 4th soon, I personally have not had an issue with the place. So far when there has been a problem they have fixed it pretty fast. This includes the few maintenance requests I have had over the last couple of years and it has been for minor issues since the apartment I got was in great condition. Overall they have not been jerks and have been helpful and understanding to me.
For the location you're 5 minutes from everything important like the Mall, major stores, Walmart and Market Street. The staff has been awesome as well as the ladies at the white house, they give free popcorn, cookies, and frozen slushies to residents. USPS, UPS, and FEDEX for the most part leave the packages at the White House so they are not stolen from outside your door.
Basically I feel safe and I am happy where I am, no bug issues either and this is coming from someone OCD about dirt and gross stuff. Not to mention I think this place is in the better part of Lewisville since it's on the border of Coppell and I'm close to my favorite Chinese restaurant.
Everyone is going to have their own experience with the place, mine so far has been positive. I'm happy and that's all that matters to me.
