I stayed at the Grand Hyatt KL for 7 nights after winding up a 2-week business trip. I have nothing but good things to say. The hotel is very new. The rooms are large, very clean and quiet, very comfortable, lots of wood, muted colors, great bed, excellent layout of space, very relaxing. All the rooms have floor to ceiling windows so you can get a great view of KL City Center, hills in the distance, approaching thunderstorms, etc. Major mall shopping nearby.
Service is excellent, English is a 2nd language for most staff but if you travel overseas you should not have real issues with that. Restaurant is very good, good wines and food, as with any hotel the menu will get a little boring if you stay long enough, but the quality is just what you'd expect from a Hyatt.
Kuala Lumpur downtown has a lot of fine hotels, but I'm a Hyatt fan and this is the best Hyatt I've stayed in yet. Michael S., Concierge Manager at this Hyatt, is top-notch in his profession.
A few little things I noticed, too small to mention here, but hopefully they will be worked out soon. Definitely worth your hard-earned money.More
