Booked for 2 weeks 6 months in advance, based on online reviews and photos :(
Filthy room, ants crawling up the walls in longgggg trails, light in bathroom was broken as was the front door light, bed headboard and frame badly damaged, sand on floor upon arrival, 2 dirty used glasses at bathroom sink (one still had lipstick on it), toothpaste in sink, constant issues with door lock, mildew around edges of bathtub, toilet stains, only 2 towels. Contacted management and housekeeping several times, nothing done except some extra towels brought on day 2. Requested a different room, was told there was none available. Nearly 2 hour wait to checkin as lobby was packed and staff was very overwhelmed. Man who helped us with our bags for our room did not even say one word to us. Wrote Sandals 3 times after our return home and they never responded. 4th and last letter to them I received a short note back saying if we wanted to book another week they would give us one night free. No thanks!
I am not a drinker but the few drinks I had over the 2 weeks were very weak. Food was average and we are not picky.
Hostess and staff at main restaurant were great however.
