When I was in KL a few years ago I stayed at the MO and it was a fantastic stay with excellent service, from airport pickup to checking out. Their breakfast was very nice, and I was in the business center using the internet while I had a cold and was coughing. One of the staff came over after hearing me cough repeatadly and offered to get me a doctor straight away. I was touched with the service throughout.
Hopefully it hasn't changed and the place is as I remember it.
