We were in Costa Rica this year in June, in our honeymoon, at the beginning of the rainy season. Initially we were supposed to stay only 2 days at Vila El Sueno at Ocotal Beach and then visit other locations in Costa Rica. But when we got there, we were wonderfully impressed by this peaceful location, with its great view over the ocean and the nice beaches around, so we decided to stay for 2 more days. Even if the rainy season had just begun, the weather was nice during the day and whenever we got a shower in the evenings, we'd found it as a real blessing.
Since the villa is just a few minutes away from Coco, we were able to go out and experience some of the local cuisine (the locals call them "SODAs", don't have any idea of what that means). The only point I would make is that the roads are in a poor condition, so if I would go to Costa Rica again, I'd definitely rent an SUV
Sandy and Dean, the property managers, were great hosts and they made us feel like home right away. They provided us with all the information needed, where to eat, what to see and what to avoid, in order for us to make the best of our time there. Even Coco, their dog, was a friendly and funny host :)
The Vila El Sueno rooms weren't so fancy, but very clean and comfortable (AC, big bed, cable TV, wifi, refrigerator). Also having access to a real kitchen made it easier to cook our own meals and store our food, when we were not in the mood for dining out. In Costa Rica it gets dark around 6pm, so in the evenings we preferred to cool ourselves in the swimming pool, while contemplating the sunset, listening to the birds and the howling monkeys :)
To conclude, I highly recommend El Sueno to anyone. I would gladly choose the same villa if I were to revisit the Guanacaste region.
