You are right of course, SG is not for everyone. However, for the hundreds of owners, either full time resident or part time, it is far from remote. It is actually a 6 minute drive from the town of Balsicas, with La Tercia and Roldan probably a few minutes further.In any of these you will find Banks, Solicitors, butchers,bakers,supermarkets,restaurants, coffee shops, hairdressers, Greengrocer, petrol station ,bars,to name but a few.
If however you run out of Tea bags, coffee, milk, bread etc, you can get these on the SG site at The Blue Palm, which is a bar, restaurant, swimming Pool and you can get a full English breakfast without leaving the site.The golf course is a 5 minute walk (with your trolley), where development is continuous and ongoing.
The Blue Plam and the Spanish Bar are open daily and, apart from food and drink, have Quiz nights, Bingo, Music evening, Race evening etc.
Going off site to shop is part of the life, as you can combine this with a trip to one of the many coffee shops with freshly baked cakes, buns, to be enjoyed sitting outside in the sun.
A 15 minute drive will take you to the town of San Javier, with it's shopping Malls and Iceland, Aldi and Lidl.
The golf course is a 5 minute walk (with your trolley), where development is continuous and ongoing.However,if you are not a golfer, then Sierra is not a place you would look for a home.
As suggested by Drumstick, visit with an open mind is the solution.
