The service of The Langham is superb. My husband and I have stayed in The Langham for 2 nights. We did not make any request, but the concierge lady upgraded us to another room. However, we heard low frequency 'hum' sound constantly. We called the service and the service manager came to our room quickly. She also heard the noise and she said it's because of the construction nearby. She has already prepared the courtyard room for us. We went together and checked and finally settled in the courtyard room. It didn't have those hum sound anymore. However, we found the noise of the air-conditioning was quite loud. The next day, we called the service again and they immediately repaired when we had our lunch. The aircon was fixed after we came back our room.
One thing that can be improved: the water of the shower is too slow.
