I have been a tenant for 3 years and the experience I have had so far is terribly poor.
Very poorly maintained building. Dirty everywhere....elevators, floors (with lots of waste stored in common areas), security/reception that has a phone that has not been working for 4 months even though the concern was raised both electronically and personally to the building management. What are you doing in case of an emergency? Who will help and respond? They have a ticket system for service requests and complaints but rarely they properly execute on those. Instead, you just get an email back reading "Your case was resolved" When? Where? Simply ridiculous. I strongly advise to avoid Rimal 1.
Also, as reported by Shadi (see previous comments): noise has been a nightmare. Drilling all day long for 4 months. And, of course, all allowed.
