Mouse poop *in* the sheets in the first room. Staff was argumentative & rude, initially offered a new room the next moring, eventually put us in a new room immediately. The next day we found the new room had ants coming out of the sink, staff was again argumentative & rude, offered to have cleaning staff address it. At this point it was almost midnight & I had yet to stay in a clean room, so I no longer felt safe & checked out immediately.
