Room service (such as dusting and moping floor) is not daily. You see roaches here, there, and everywhere. Killed more than 10 roaches, sizes from tiny to small to medium.
No big flying ones. Location is great. MTR station is downstairs near the corner of street. Take out and sit in restaurants far and near. Lastly, I had problem with door lock but hotel owner sent repair staff to fix it pretty soon. I need to be taught how to close the door; otherwise, it may not be locked.
