This apartment location is amazing. Easy to access to I-270, close to all the stores and Rio. The staffs are friendly and helpful. Some maintenance needed, but I think it is overall good place to live.

Overall, this is a very clean and well-maintained apartment community. The environment feels safe and secure — access to the parking garage requires a key fob, which adds an extra layer of security. The amenities are excellent, including a swimming pool, gym, and even a small convenience shop for snacks. Maintenance has also been very responsive and efficient whenever needed, which is a big plus. The only downside is the mandatory contract with Verizon. Residents are required to pay around $120 per month for a bundled internet and TV package (100 Mbps download / 100 Mbps upload). Unless the leasing office provides a specific waiver or discount, this fee is mandatory. For residents who don’t watch TV, this package isn’t very cost-effective. It would be much more reasonable if there were flexible pricing options (for example, around $40–$100 depending on internet speed). I’ve also heard from the leasing office that the apartment management may renegotiate the contract with Verizon in the future — hopefully there will be some improvements. Aside from this, it’s a great place to live.
