So far they've been great!
I've lived in two buildings in the last 1.5 years that are both managed by Brookfield and they are great! Response to issues is very quick. I usually get a call or email back same day or next day even if it's acknowledgement that they received my voice mail/email. They are helpful and ensure they send someone to review the current issue at hand. I've had several issues with this condo from a noisy HVAC system to a water leak in my bedroom. The buzzing coming from the HVAC system was fixed in several days and the leak in the bedroom was fixed in less than 7 days by assessing it was pipes from the condo above me leaking down the walls. They cut out a portion of the wall, fixed the pipe upstairs, let the wall dry out and replaced it so it looked brand new - in less than 7 days. I'm impressed!
