We always like Intercontinental. However, this time, we encountered a very toxic chemical smelt in the morning before the check-out. It's like the whole room is soaked in the super glue or even worse. I pointed this out at the counter, and they apologized and explained that there might be some maintenance or construction. I would have expected some more professional response--at least, an official explanation for what my family had taken in the morning.
Besides this, the facility and the restaurant are of a regular quality level.
