Location
June 20, 2025 - Review from Apartments.comFor the price of the apartments, having the nice view of the lake is great. Especially with the trail going around it. Its also relatively close to the mall and other shopping centers. But not too close so traffic isn't terrible near the apartments. Definitely worth the price to live here.Property Manager Responded

Excellent neighborhood to live in!
December 15, 2021 - Review from Apartments.comLived here for 8 months while waiting for our new build to be finished. My family and I felt safe, and we met many wonderful neighbors along the way. The staff is courteous, professional, and they offer many fun activities for residents throughout the year. Definitely a great renting option for families with kids, single people, empty nesters, elderly, military, and civilian alike. Also, you cannot beat the location and amenities.Property Manager Responded
