I stayed at the Four Points Manhattan this week.
There are 22 floors, and 8 small rooms per floor. No platinum upgrade offered. I'm not sure if they have any suites, and if they do, where they would be.
The beds are comfortable, nearly as good as the Sheraton beds. Although the rooms are small, oddly enough the bathrooms are spacious for NYC (and are brand new remodeled).
Free internet is wired (ISP is Wayport). Fast and reliable. Bring your own cable.
Avoid the odd numbered floors. These have an industrial-size ice machine sitting in the cramped hallway, that comes on every hour and runs for 15 minutes or so, as loud as a jet engine. On open space under the room door means there is no sound insulation from hallway noise.
