That twin room (b) is only for the room located in the second floor which is very loud. Need to pay extra to get rid of second floor. I do not suggest this room style. The hotel is far from metro station. Also, the hotel entrance is not near the main road, it is a bit hard to find for the first time.Service and amenities are what you may expect at this price range. It is one of the best budget hotel around Liwan area.
