The place is very clean and also well maintained. The staff including the security personnel are well trained and disciplined but could be a bit harsh if you rub them off the wrong way. The main problem is getting an entry pass into the area. If there's a lot of people, you're probably going to have to wait for long since there are not many counters providing entry passes in the area. So if you are visiting for some important appointment, make sure you reach a bit earlier to ensure you get in on time.
