My family had a very enjoyable stay at La Tintinki. Here were the pros and cons:
Pros: Lizette and her husband were very helpful in answering our questions and getting us situated. They also had a six pack of beer, some baked goods, and various other treats ready for us upon arrival, which was a nice touch. The place is very close to the beach and has its own small pool which my two young kids liked. The beach is very calm and shallow for probably the first 100 meters out. The house was close to many ruins and cenotes, some of which we visited and enjoyed very much. Everything was very inexpensive which was another perk. We felt very safe the entire time we were there and the locals were very helpful and patient with my limited Spanish.
Cons: The house only has air conditioning in the bedroom, not the whole house which made it pretty hot at night in the kids' bedroom and the living room especially after closing and locking the doors for the night. The first night we were bombarded by mosquitos and ended up smashing dozens before we could settle down for the night. I'm not sure why they were so bad upon arrival, but we were able to get them under control and then were extra vigilent about making sure the screens were always shut. After that, we didn't have any additional problems with mosquitos inside the house. Also, outside the mosquitos were mostly bad at night so we didn't really go outside after dark. During the day, they were virtually non-existent.
Some additional considerations about the area: If you are from the US or Canada, it would be helpful to know some Spanish as very few locals speak English. It is very helpful for getting around. Also, you will need a car if you want to travel around the area. Lizette offered us hers for a reasonable price, but we opted to rent and had no problem driving around in the Yucatan State. You will have to go to Progreso to use an ATM or find an establishment that accepts credit cards, so bring plenty of cash/pesos.
Overall, we had a very nice time and would return in the future. Thank you Lizette and Gino for the wonderful stay at your house.
