We chose Barra de Potosi for a few reasons. Summer swells up the coast meant the waves would likely be too much for the three little ones in tow (aged 7 - 9.) So too, being near to Zihua and not actually in it seemed totally sufficient. As it turned out, the latter was an understatement. Zihuatanejo remains endearing in its own right but, compared to our oasis, we only visited once mainly to pat ourselves on the back regarding our (my!) brilliant decision to base our selves down the coast 20 minutes in Naomi's terrific house.
The house itself was very well appointed, very spacious in design, well shaded where needed, and, at least for us, provided a constant and heavenly rotation of beach, pool, kitchen, hammock with book, cricket in the front area (well shaded and replete with cacti and other local flora), repeat...
Tito was a wonder and worked out fishing and horse riding for us in seconds. We didn't use the lovely cleaner for anything more than cleaning but ... she did a great job.
The restaurant on the beach about 45 seconds' walk to the left was also the perfect spot for a few lunches. Cheap, delicious, amusing, limited hawkers. It was also fun that the restaurant area to the left was such a hot spot for the locals on the weekends. No one in front of our house but an amusing array of people to the left enjoying the waves and toasty water.
We are planning my wife's 50th back down there in a few years already!
