This is one of my favorite hotels to stay and I always have to stay here when I'm in KL. The service here is seriously incredible. My first stay here was when this hotel had just opened and I was a bit worried they were still figuring things out.
Well, I was wrong. Upon check in they've always upgraded me to one of their largest suites for being a Platinum member. Also they always made sure I'd have a room with a clear view of the Petronas Towers. Not only that, they hand-delivered delicious complimentary cocktails and desserts to my room for being a loyal Marriott member. What have I received at other Marriotts? Maybe cookies or decent macaroons.
Then on one of the nights, my friend and I went to the club/pool area and noticed it was completely packed while all the tables had high minimums. One of the hotel managers who I barely conversed with a few days prior, noticed me, correctly addressed me by name, and then gave us one of the best tables free of charge. Again, incredible service.
The breakfast buffet selection is also incredible. Malay, western, freshly made items, and exotic fruits. Though the selection doesn't change too much every day which is only an issue if you're staying at the W for several days. The breakfast was comped for elites, so I didn't mind.
