Our room was located on one of the upper "Cross" floors. The room was very clean and quite spacious, with a large, comfy bed and a separate seating area with a desk.
Despite being on a higher floor, the windows didn't do much to dampen the street noise at night, but it didn't really bother us too much.
A nice bonus was that our floor also granted us daily access to the lounge with free drinks and snacks.
There are only two elevators, which unfortunately, could be a bit of a wait at times.
Lastly, the breakfast buffet was excellent, with a lot of different Japanese and Western options.
