We loved it.
From the very first contact with the Dervil team, we were in good hands: responsive, gracious and informative, willing to answer a myriad of questions asked by two people who had never been to North Captiva. They continued to help us throughout our stay -- we even got a call from the owner checking on us. It was like having a private concierge service. We cannot say enough. Their enthusiasm for the property was evident, and as soon as you pull into the driveway, it is clear why. Rounding the turn in your golf cart, you are transported, your tropical vacation has begun. Echoing previous reviews, the kitchen is well stocked (waffle iron!), the views are excellent, from so many spots in the house. Truly steps to the beach...and the pictures don't do it justice. We enjoyed Stella Maris so much we ate all our meals there. We could not tear ourselves from the view: days began with sunrise on the roof, went till sunset over the Gulf, and ended watching satellites pass overhead from the hot tub.
A note about the island itself: do not let the need to pre-order and pack in all your food deter you. A tiny bit of planning (and Dervil will help) is all it takes to make your stay perfect. The proximity and diversity of wildlife more than compensate for the sparsely stocked convenience stores. This is closer to a Caribbean villa rental than a Florida beach vacation. We were happy to trade Walmart convenience for the luxury of quiet, uncrowded beaches, beautiful water, and having nature close to hand.
