This is a very spacious, comfortable and well equipped villa. The interior decoration is clean and modern with nice quality furniture. It's very large, with lots of space for around 8 (we were a family of 5 so every child had their own room).
The outdoor area is also well maintained and the heated pool is very pleasant. On the cooler days the pool temperature was a little too fresh but on the warmer days it's quite comfortable and warmer than the sea.
Overall there are no real negatives except the WiFi speed is quite slow. You pay for it yourself on arrival, it's easy to set up (getting a PayPal account in advance would be best), but there's no option to have a faster speed which is a shame - a small thing really though.
Also we didn't particularly like the town of Caleta, it's too British. But the town beach is pleasant, and there are some nice restaurants (although very few typical of the island, for that you need to head out). However in terms of location the town/Villa are ideal because they are central, so you can easily explore the island and it's only 10 minutes from the beach and airport.
Finally, having visited many of the other islands, we weren't sure if Fuerteventura would compare as favourably. It most definitely does, it's probably our favourite. The landscapes are beautiful, the beaches are amazing, more so than other islands, and there's so much to see and do. BUT you really need a car, and also for the villa which is about 3 km up a hill from the town beach. Driving here is so easy and cheap (rental and fuel).
Overall, if you book this villa you can be absolutely confident you will have a great standard of accommodation with owners who communicate immediately and helpfully. Get yourself a car and discover the island.
