We bought a Villa with a pool and would not now want to be without it. We have a maintenance contract which includes the pool so we don't have to look after it ourselves.
The thing we both like about the pool is the privacy and the convenience. We can sit outside all day, pop in the house for drinks, snacks, have lunch by the pool, have a dip and then if we want to go into the house and get changed. We don't have to share a pool with other people and we don't have to go to the beach, it's absolute heaven, cannot think of anything nicer than sitting quietly by the pool totally relaxed and reading a good book in peace with no distractions.
