Stayed there back in June.
Staff were very friendly. Upon check-in and seeing that I was a Gold member, the front desk agent took me to a seperate desk and sat me down to check me in there. He asked whether I needed anything during the stay and asked me what time I wanted to get up and check out. They didn't even take my credit card number during the entire check-in process. They then took me all the way up to my room. They discourage tipping as 10% service charge is already added to the bill.
There's no executive floor and lounge at this hotel. I was given a corner room on the top floor.
Breakfast coupon was given without asking. The coupon was only good for continental breakfast but when I got to the restaurant, I was told to just help myself to the buffet breakfast (which was VERY good - western and japanese style.)
If you are staying in the airport area, I highly recommend this hotel.
Feel free to ask if you have any other questions!
