We thoroughly enjoyed our stay at Villa Dunas! Having been to Corralejo several times before, I was totally aware of the location, and it was great to have uninterrupted views (and sun rises) to the Sand dunes in the distance. As already stated, you’ll need a car.
My boys (7 & 4) particularly loved the outside spaces (front and rear), and we used the mini golf and jacuzzi regularly - plenty of space to run around for them, and very peaceful (felt like we had the whole area to ourselves)
Inside, the property is spacious for 4, and can easily handle 6. Although didn’t really use the roof top, this was excellent too.
Only real ‘criticism’ is the inside of the property (furnishings and bathrooms) are beginning to feel tired, as these properties are 10 years old now - have flagged a few things to the owners, who’ve said they’ll fix them.
Just in terms of anyone else going at this time of year, the complex pool is not worth thinking about. It is totally ‘dead’ (ie no one else uses it, and no sun loungers - feels like a ghost town), and the pools are not heated, so freezing! Better to go to one of the hotels (we used the Rui palace tres islas, on the dunes/sea) and use their pool! - most have an least one of their pools heated - makes it just cold, rather than freezing.
Ps. Local supermarket (Mercado) is excellent value compared to the ‘Super Dino’ ones in town, which cater for the tourists.
