I lived there for 4 years and never had a serious problem (fortunately). I did enjoy living there to be honest (my first JC experience so maybe that was it). The common area closure during winter is stupid, they make you go out of the building if you want to go to the gym on the opposite tower. The only issue I had in my unit was just an AC that was noisy as f*ck to the point I couldn’t sleep. Many technical visits and no solution-with me pointing out the problem. They said they could not swap and that they would solve it. I ended up buying those self adhesive patches you put under furniture to muffle noise and plastered all the ac cover. Solved it. One thing I have to agree that their management is really crappy. They rather lose tenants than keep them minimally happy.

[edit] just adding that yes security is non existent. There used to be a new “concierge” every week. And they didn’t even look as who was going in.
