The Armstrong at Knox offers an excellent location near Katy Trail with well-maintained amenities, spacious units, and responsive leasing and management staff.

Billing discrepancies and security concerns in the parking garage have also been noted by some residents.

Management and leasing staff receive consistently high praise for responsiveness, professionalism, and genuine care for residents. Leasing representatives are noted as accommodating and helpful throughout the move-in process, while property managers are described as accessible and communicative. However, some residents report billing delays, unresponsive follow-up on referral payments, and inconsistent handling of maintenance issues and move-out charges across different management periods.

The building experiences persistent issues with fire alarm malfunctions, elevator reliability, and noise insulation. Multiple residents report frequent fire alarms disrupting sleep at irregular hours, slow or non-functional elevators requiring extended waits, and poor sound isolation between units. While the location, amenities, and some staff are praised, these building condition and maintenance concerns significantly impact resident quality of life.

Residents praise the property's location, amenities (gym, pool, outdoor putting green), and responsive management staff. However, recurring concerns include slow elevators, noise transmission between units, fire alarm issues, and maintenance responsiveness gaps. The property offers well-maintained shared spaces in a convenient neighborhood, though building systems and soundproofing present ongoing challenges.

The property benefits from an excellent location with convenient access to nearby retail, restaurants, Trader Joe's, and the Katy Trail, plus resident-restricted parking that is easy to navigate.
