it’s good…until it isn’t…

Well….it’s a roof over your head (until water floods through your ceiling lights).
A place to wash and dry your clothes (unless your dryer is broken for 2 1/2 months with no end in sight of it being fixed).
A safe haven for you and your family (oh wait…management has a “broken” master key to your apartment and needs to take yours for 2 days so you have no way to enter your apartment if it’s locked).
A clean, well-kept community (sorry - I have the wrong place. This one will block all your...
cars in when it snows, won’t clear the walkways sufficiently, paints over water damage from earlier said roof flood without checking for mold even when asked).
A responsive management (if you count never picking up the phone in the entire 2 years that I lived there or responding to at least 50% of my calls).
A well-organized management (except for when they wouldn’t complete the necessary forms to help us move out, give us move out procedures, etc unless I physically walked in a demanded so)
A sense of community (they try with this one. Until you get the millionth email saying “DOG POOP. CLEAN THE DOG POOP” sent to the entire community in a week)

Save yourself the overpriced headache of a roof over your head. If you want to spend this amount of money on an apartment, you can certainly do that somewhere else for better quality.

Property Manager at Boulders at Katy Trail responded to this review

Hi there,

Thank you for taking the time to share your feedback with us. We are truly sorry to hear about the many challenges you experienced during your residency. It sounds like you encountered significant frustrations with both building...
maintenance and management responsiveness, and we understand how incredibly disheartening that must have been.

We are particularly concerned to read about the issues you faced with water intrusion through ceiling lights, the extended period your dryer was out of service, and the disruption caused by the master key situation. The fact that your vehicle was blocked in during snowy weather and that walkways were not adequately cleared is also a serious concern, and we apologize for the inconvenience and discomfort these situations caused. We also regret to learn that water damage was painted over without a thorough check for mold, and that your move-out procedures were not handled efficiently.

We are committed to providing a positive living experience for all our residents, and it's clear we fell short of that goal for you. We would like to discuss these matters further and see if there is anything we can do to address your concerns. Please reach out to us at (636) 477-7770 at your earliest convenience.

I love this complex!

I have visited Katy Trails several times, and after I graduate college I plan to call it my home. The manager was so sweet and welcoming!

Do not be tempted to live here

The managers and maintenance is absolutely horrible for the amount of money and level of service Katy trails claims to provide. You can see by the people moving out and people moving in just how horrible it has become. The management and matinee have been slow to respond or unresponsive even when it comes to issues. The apartments seem nice but are horribly constructed with the cheapest materials. As a commercial general contractor they should be embarrassed. I know resort and luxury apartments... use things that are easily available and uniform. That usually falls into a cheaper category, but this complex goes above and beyond to cut corners to provide the cheapest and worst quality flooring, cabinets, appliances, and utilities. They will expect you to pay for things at outlandish prices as well such as carpet to make even more money. Save yourself the time and headache of living in this community. I was excited to leave this place, like most of residents that have watched the changes as they charge more and give you less.

Beautiful Complex

We’ve lived here for over a year now and we have nothing but good things to say. The neighborhood is quiet, the neighbors are friendly and the property staff are amazing and helpful. This is one of the best apartment complex in Saint Charles!
