Via Las Colinas is a great place to live. The location is very convenient - lots of shopping, restaurants, and access to major highways. Having a DART station across the street is very nice as well. The complex is fairly easy to reach, although coming from the west forces you to have to go through the Phase I speed bumps. I like the safety and speed control they promote, but they are annoyingly jarring.
The unit itself is really nicely constructed. The features, which include granite counter tops and stainless steel appliances, are very new and in good condition. The building itself is solid - haven't had any issues with noisy neighbors. Not that I can't hear them on occasion, but the materials are somewhat soundproof. I live on the third floor and there is nobody above me, so I cannot attest to the noise level of upstairs neighbors, which seems to be an issue everywhere.
The only issues that are worth mentioning are the spiders, wasps, and numerous other bugs. Of course, take this with a grain of salt, as the building is situated right next to Lake Caroline, so this is to be expected. I would suggest investing in some spray that kills spiders and other bugs. Being able to park right outside your building is sometimes impossible but it's not a huge inconvenience unless you have groceries.
Overall, I would highly recommend Via Las Colinas. It is a nice community based on both the people that live and work here, as well as the complex itself. I have been thoroughly spoiled in my first apartment experience and will miss living here.
