We had a lovely stay at the Villa Oleandro. Before and during the stay communication with Manuel and Giancarlo was friendly & clear and Giancarlo also provided some excellent recommendations for activities and places to eat - we tried a number of them and all were perfect.
The villa is well-located to explore the north western part of Sicily, although a car is essential. Castellemare di Golfo and Tonnara di Scopello are only 10-15 mins away. Segesta, San Vito lo Capo within 30-45 minutes. The villa itself is on a private estate with other villas and in a very quiet location - literally all we could hear most of the time were cicadas. The grounds are immaculately kept and beautiful with amazing views of mountain peaks directly behind and in front and the kids loved the pool. There are mosquitos however, so bring defences.
Inside, as other reviews have noted the bedrooms are under the house which is a neat and energy efficient solution to the heat - it stays a constant, cool temperature all day/night and air-con isn't needed. There are light wells but inevitably not much natural light gets down there. Whether this works for you is down to personal preference. I was fine with it, as mostly it's a place to only store clothes and sleep, but my wife less so.
There were only a couple of slight downsides. The broadband uses a 4G dongle and is difficult to get working / temperamental. It's also capped at 10GB before charges which is not ideal if you have young children who stream content. In the end we simply used a mobile phone as a hotspot. Also we found the kitchen to be a little tired and could do with an upgrade. The rest of the villa is lovely however and decorated in traditional Sicilian style with a large outdoor space for cooking, relaxing, swimming and BBQ. Overall I would very much recommend staying here.
