This company manages a condominium site at 1500 Lake Shore. There are about 50 units. Some people are owners, some are renters. They have allowed some people in that do not know how to behave around others. My upstairs neighbors have a "disturbed" child who pounds the floor all day and night and even though I have complained, they have yet to take action. This affects my "quiet enjoyment" in the unit I own below. I will either have to sue Triliji and the upstairs neighbors or sell my unit. I think they are in cahoots together. Be aware they do not screen tenants well or require them to read the lease and act accordingly or be evicted. I lived in the California Bay Area, and if you did not behave properly, you would be evicted.
