I did not hear of a private jacuzzi. There is bird life around the resort and my wife and a guide saw a fresh jaguar foot print on a day hike. This is a lovely resort but is far from "civilization." It is self-contained, even to having its own organic garden. All the sights are by day trips and be well advised, bring walking shoes, rain gear, insect and sun repellent, a water bottle, etc.
Not all villas have WiFi, but we had the FFC Villa and the 2BR Villa next door, and the wifi was great. There is also wifi at the main Lodge, but things are spread out so that would be a pain to bring your laptop, but since that is where main restaurant is there is no problem checking on phone 2 or 3 times per day.
