I had some really bad experience with Sunway Hospital recently.
My mom was hospitalised two months back and they have conveniently "lost" our medicine without us knowing. FYI, the medicine was a targeted cancer medicine - if you're familiar with this, you'll know that they are really expensive. Suffice to say it was a very unpleasant experience.

I'm not trying to discourage people from going to Sunway but if you really do, just be extra vigilant with your belongings and medicines so that they wont be missing later.

You can pm me if you want more information about my experience. I can elaborate more on the details.
