Tranquility Bay Beachfront Hotel and Resort

10/10 Excellent
"Villa was clean. Staff was very polite, knowledgeable. There was a problem with the toilet and it was taken care of. A shower outside of the pool area would be very helpful in washing off sandy feet, also a door mat. Silverware was very cheap, could be better. It's the small things that could make it great."

8/10 Good
"Our villa was right next to the workers building. Not an ideal spot for a “premium” villa. Also when they were cutting lawn and blowing leaves they were blowing everything all over our rental cars. Parking was tough because I think employees were also parking in guest spots. Again I think this was due to the location of our villa. We were never told what to do with our garbage or if housekeeping would come clean. Found out later you need to specifically request it 24 hrs in advance. It was off season so nice and quite not too many people so they definitely could have put us elsewhere. Other than that we really enjoyed ourselves and plan to go back next time we would just be specific on check in about the location they put us in."
