We spent a week at Kaz Tibou in mid-February 2017, and as found the villa to be even better than it seemed on this site. The other glowing reviews are accurate - it is very well appointed, stylish, close to amenities, hikes and sightseeing in the Guadeloupe National Park (go north on the N1, then west on D23), and the beaches aren't that far of a drive away (we enjoyed the two main ones at Deshaies the most). The villa has pretty much all the creature comforts you might want - a very well set-up modern kitchen, two air conditioned bedrooms, a walk-out terrace that holds the dinner table, lounge chairs, jacuzzi and shower, and leads out to a gorgeous tropical yard. The living room is very nice, with couch, TV, stereo (though the weather was excellent, so we didn't use it much). The location, in the low hills on the outskirts of Petit Bourg, is pretty central, and most of Basse-Terre and a fair amount of Grande-Terre are reasonably close.
Isabelle and Sylvain are excellent hosts - very welcoming, full of information, available to answer questions, and with ideas about things to do. We arrived late afternoon on a Sunday, and they helped us out with a very nice dinner and dessert. They have a small binder with a lot of information about the villa and the island, and this was really well done.
It helps a lot if you can read and speak French, but Isabelle and Sylvain are very welcoming (the binder is in French and English), and there is a general friendliness and openness on the island. We saw people who spoke very little French managing their way around just fine, and they treated in a welcoming manner at a number of spots on the island.
Isabelle and Sylvain, thank you very much for everything, and especially for the recipe for the coconut flan!,
