We stayed at the Trump late last year. The entire property is immaculate, smoke-free, and far away from the standard Vegas scene, if that's what you're looking for. The downstairs restaurant and lounge were very memorable, and every room is a suite. We were able to fit in a few games of pool on their tables near the lobby.
Only problem is the location. It's quite a walk to the strip, so cabbing it is a must. The complimentary shuttles are always packed, but it's an option. Also, there's no downstairs casino, so if you get the urge to play late at night, you're quickly discouraged by the lack of proximity to a machine or table.
Edit: Accidentally left a few items in the room on my departure: an electric toothbrush and a nearly-full bottle of D&G cologne. Called to see if they could ship them to me. Guess which one they couldn't find. I received my toothbrush by mail fairly quickly.
