Review for Big M Casino - Little River Review For Cosmopolitan Casino Google User Mar 21 '18 at 10:47 My wife and i recently enjoyed a seven day stay in sunny Las Vegas. We stayed at the Cosmo this time, and it was phenomenal. This place pulls out all the stops to accommodate their guests. They do all they can to make you feel right at home. The rooms are Beautiful and always promptly cleaned. I was so very impressed with the place. Would recommend to anyone visiting Sin City. View full site to comment or like
