Fred,
It's "San Miguel", not San Jose.
It is a very special town. It's located in the middle of Mexico, in the high plains (about 6,200 ft above sea level). Because of this the climate is very mild and consistent. Beautiful all year.
The town itself is old, from the colonial period, with cobblestone streets, flowers everywhere, brightly painted houses and a great deal of man-made and natural beauty. It's located 3 hours north of Mexico city, 6 hours south of Texas, 8 hours from the Pacific and 6 hours from the Atlantic. Like I said, right in the middle of the country. It has no airport. It has no industry.
San Miguel is a Mexican "National Monument" and was also declared a "World Heritage Site" by the UN a couple of years ago. It is popular with Americas and Canadian in the winter because of the warm weather. It's popular with people from Mexico City as a "get-away", vacation spot; a place to have weddings and such. It's popular with Texans and others from the US southwest during the summer when it's very hot up north, (north of SMA at least) because its summers are cool.
The cost of living in Mexico is about 1/3rd to 1/2 of that in the northern US and Canada. Add it all together, and if like me one can work wherever there's a high-speed internet connection, the attraction in considerable.
Oh yes, crime? Not an issue here. San Miguel is safer than Toronto, or any big city for that matter. The drug wars that are in the press take place in the Texas and California border towns, hundreds of miles away. The worst crimes seen here are car break-ins, and then not that often. The cops mainly direct traffic.
So, as the saying goes – What's not to like?
