Showing 8 highest rated

Metroline Flats has been our home for over 6 months now! We really love the staff and location! Althea at the leasing office is so amazing and nice! Our dog absolutely loves her! He charges into her office everyday to say hi! The building is always clean and Roy, the Maintenance Supervisor does a great job fixing anything our apartment needs! Our apartment’s finishes and size are nicer and bigger than most other complexes we looked at, and seems like a good value for the area! Definitely recommend!
