The hotel is overrated. The furniture in the rooms are filthy, and with so much condensation the floors are a fall hazard. Poor quality Wi-Fi and we’re charged $5 for utensils for our room service order. We could never reach the front desk even prior to check in to set up special in room services. The staff was very lackadaisical. This anniversary stay was very disappointing.
