Karen was most helpful and Ricardo was teriffic at certifying the two teenagers. We had wonderful dives with him and enjoyed endless snorkeling right in front of the house. Loved Paradise Beach for Christmas day and were totally entertained by the cruise ship cabaret singers and dancers who had the day off. Only problem was not enough hot water at house. Karen was working with Daniel to solve the problem. We can highly reccommend the house and staff, plus Cozumel in general. We felt very safe there and went into town frequently without any problems. Enjoyed shopping for meals and eating at various restaurants in old town. Thank you Nicolas!
