This was the best experience I've ever had at a testing center. It felt like the stress melted off my shoulders when the staff greeted me. They were smiling and seemed to truly care about how I did on my exam. So much so that they took the time afterward to ask me how it went, reassure me, and say that they hope to see me again for the next big test.
The place was clean and quiet, and they were very quick about getting me in and out of the testing area for breaks.
Good luck!
