The description of the house does not claim to have a private pool. It states that the pool is shared among the houses, although the majority of the time you have the pool to yourselves as it is very quiet and peaceful. Regarding the water supply, we own the house and are a family of six who regularly take the grandparents to to house and the water supply is always plentiful. As no problem was reported by the 8 guests during their stay, I will need to investigate if there was some other problem at that time. In our 6 years of owning the house we have encountered no problem at all with the abundance of water for showers, appliances etc, and we have never had it brought to our attention by any previous guest.
