Hotel has been opened for a while, but staff seems not familiar with the facilities within the hotel complex. One of the restaurants, Mesa, is located on the third floor which is the same floor as the garden. I had reservation at the restaurant and left my room 10 minutes before thinking that I should be there on time. However, they did not allow access through the third floor. I checked with the security guard on duty and he told me to go to the 2nd floor and go to the east gate direction. When I reached 2nd floor, there was no sign whatsoever showing the direction to the restaurant. I checked with staff working at the shops and they couldn't tell how to get to the restaurant. I ended up spending over 30 minutes to reach the restaurant. Eventually I figured out myself that the simplest access only takes much less than 10 minutes from my room.
The consolation was the food, service and ambience of Mesa were all exceptional. It's really worth trying.
I believe the hotel has close to 1,000 rooms but the size of the gym was just around 2,000 square feet with not a whole lot of equipment. It is totally out of proportion. There was no steam room or sauna in the changing room. That's a bit below expectation for a 5-star hotel. Isn't it?
