We spent 2 weeks at Casa Tranquila in December and early January with side trips to Chetumal, Bacalar and Mahahual. Casa Tranquila is a wonderful house, well furnished and equipped(we cooked many meals) with on site caretakers who make sure the beach is clean every morning and keep the house in good running order and are there to assist but not intrude. As noted the house has solar, wind and generator power so there were no issues with electricity. Water pressure was great and hot!! The water in front of the house is shallow but fish abound, we snorkeled often and saw schools in several locations, even a couple of curious barracuda. The road in front of the house is barely traveled but luckily local people selling fish, shrimp and vegetables appear a few times a week with excellent product. We even bought home made flan from a couple of kids on a motorbike which was great. We visited Xcalak Caribe, had a great lunch and even better conversation with Freddy the owner. The Leaky Palapa lived up to all the wonderful comments. People at XTC dive center were very helpful with information, Senior Felipe Fonseca helped us get our National Park passes and Moyses who is the local agent gave us our keys and got us off to a great start. Mike owns the house and was excellent to deal with, before, during and after our visit. Never met him but he was available by email whenever we needed something or had a question. We used a collapsible cooler on wheels as a piece of luggage which made it easier to shop for food in Tulum before we arrived. Bring food, supplement with local purchases and restaurants, swim and RELAX.
