    Great hotel, stinky due to sargassum

    Clean, friendly staff, accommodating. Balcony was nice

    Sargassum on beach, unusable area, very stinky with piles of seaweed that needed to be removed from the area to decrease the stench. Took away from enjoying all the features available at the hotel. The espresso machine was a bit much, need standard coffee/kcup option

    Relaxing with a great view.

    The property was set back from the roadway and close to the water.

    The sargassum grass smelled bad.
