As always, full reviews and photos are in the respective master threads:

I liked the Sheraton and Hotel Bristol the best - the Sheraton honestly got everything right, but Bristol has a better location and more charm while trading off a worse shower than the Sheraton. I would rank Hotel Verte next, which I enjoyed everything but the breakfast quality. After that, I would rank the Westin, which had a great bed but needs some updating, especially in the bathroom. Then, I would put the Marriott, which needs serious updating and improvement to the bed (though, I liked the Marriott breakfast better than the Westin breakfast). For airport stays, the Renaissance works.
