Very bad experience this time.. Housekeeping was well below standard. There were visible stains on the bed covers..!! Seems like it had not been changed after the previous guest used the room.. I saw a couple of cockroaches in the room as well. One was crawling around where the tea/coffee set up was placed, and another was crawling on the wall.. Never expected something like this from a Sheraton hotel..
