It is located in 85 Tower where most of our conventions are held. The "Hotel" is owned by several different companies, and so you may find the room next to you under a different theme and management.
Rooms are really spacious - mine was about 300 sqft. Nice and cool A/C during summer months. Towels, basic necessities and a hair-dryer (with enough power) are provided. The decor feels more like a studio apartment (without kitchen) than a hotel. I love the feeling of home.
Staff is very friendly. As there are many rooms on each floor, walking from the elevator lobby to your room may take a while, and you will need to transfer at the lobby floor on 12/F to another elevator before you can reach the ground floor.
Overall great experience.
