Hi there,
The Maya Beach Hotel would be a great choice as you can choose between standard, deluxe rooms or book one of the
apartment style villas. These apartment/villa style units offer the amenities you are looking for such as air conditioning, and extras such as a jet tub, etc.
Another great recommendation would be the Ranguana Lodge, which is located in the heart of
Placencia and closse to all the restaurants and shops. The Ranguana lodge offers beachfront cabins featuring two double beds, air conditioning, private bath, etc.
Hope this helps
