Its hard to find anything to complain about. Perhaps the only complaint is that warm water dissipates quickly in the shower during winter. Havent had that experience elsewhere.

I like the building and the amenities are good. I really dislike the parking situation as you have to pay for visitor parking every time. Other buildings will give you at least some comp parking passes for your guests per month
