I always had good experience in this hotel, with friendly staffs at each level. In each room, there is a tag where the hotel suggested not to change bed sheet every day for green. After the first day of stay I placed it on the bed and only the day afterwards I realized that there was a shoe print clearly at the end of the bed. Therefore I left the tag on the table. However, when I came back from outside I noticed that the sheet hadn't changed at all (still had the shoe print in the same area).
I do hope the hotel can communicate well with room attendants on this green policy and pay more attention to the cleanliness of the room. Other than this issue the room is very clean and tidy.
