I just completed a 3 night stay at the M and the experience was fantastic. I followed some suggestions as posted by others to request for a room upgrade - if available. To my surprise, they moved us to a corner "larger king room". I am just silver elite. I was very pleased w/ the service because the only room available was a queen or double for the rate booked. Also, when arriving to the hotel, my folio was already checked in and the person just handed me a pair of keys. Really great service and would return again.
The M bar has some great happy hours and drink specials. Illy coffee shop is also great for espressos and cappuccinos.
