We stayed for a week in Liesbet's villa this summer. The description of the house as stated on this site is very accurate. The house is spacious and has everything you need and expect from a high-end family villa.
We especially liked the terrace at the back of the house with a great view of the Montgo mountain. We spent several days just relaxing on the terrace in the shade and swimming in the pool, enjoying the great view.
The villa is situated in a big residential area with many other villa's, but when you're sitting in the back garden overlooking the golfcourse, there's a lot of privacy and you don't notice the other villa's much.
I would recommend a rental car to travel to the several beaches in the area (we especially loved the Arenal beach in Javea!), to the supermarkets and to explore the area, although you could also do that by bicycle if you're sporty enough.
Liesbet was a perfect host with great tips about the area. Everything in the villa is up to the standard that you would expect from a holiday villa and it's situated perfectly for exploring the beautiful Costa Blanca area with the family!
