Jungle Creek is located a short drive from the entrance to Manuel Antonio (where you will have to pay to park, just make sure not to park too early). The house we rented was big and clean, and it had air conditioning. The appliances may not be stainless steel, but for the price we paid it was amazing to have a full kitchen and two bedrooms.
The owners are nice and friendly and my whole family felt welcome. My kids loved the pool and the free wifi.
We would stay here again if we return to Manuel Antonio.
