Couch in the suite was disgusting. Very dirty. Staff was great and very accommodating. Bring your own blow dryer, was less than 2 feet long. Had to bend over to use it and it kept falling out of the wall. Probably won’t return

food and beverage here is mediocre to poor. * "specialty" drink of the day was nothing more than pre-made sangria out of a pitcher * breakfast buffet has poor selection for a high-end property. no better than a courtyard. * breakfast buffet food was stale, perhaps a day old and re-heated * slow service * terrible coffee
