The Lakeshore has the view if you get a lakeview room, but other than that I'm not sure. I don't think there are a lof of suites there either.

The W City Center is right next to the "L" Quincy stop, again not a lot of suites like the W Lakeshore but I rate the property as significantly better than the Lakeshore having stayed at both multiple times.

As for the Westin's, I can't comment on them as I haven't stayed there, but having seen the locations of both - they are both convenient and I don't really ever have many sub-standard experiences with Westin's.

Best of luck!
