We stayed in both the superior quadruple room and the standard double room. The former is excellent and we give a five-star rating for that stay. However, when we changed to the front/street side double room, it is not as nice as the previous one at all. Of course, the front desk staffs are always very friendly and courtesy. The problem is that the front side is not as quiet as the back side. To be fair, for the most of the night it was pretty quiet. But there were just a couple of cars whizzing past the street below Very early in the morning, like 5 o'clock, enough to waken us. The bigger problem is the sewage smell always come out from the bathroom. I believe there is a problem with the U-shaped pipes or something.
