The manager Dennis is professional. He called me on Monday when the office is closed to inform me about the unit I wanted, eventhough it wasn't available. I'm impressed with their service. I highly recommend them.

Report
A new management company has taken over and is the absolute worst there is. They are nasty, rude, unhelpful and do not return calls in a timely manner. we have been long time tenants there and area saddened to see the awful changes. They changed their access hours at the gate and the hours the office is open is just not convenient. they also completely changed their online payment system and it is very difficult to follow. DO NOT rent here. you WILL regret it if you do. honestly, we loved it here until the past year or so. it saddens me to see this great little place become a corporate, greedy
