Puerto Escondido is relatively unspoilt and has NO major chain hotel or tourist infrastructure. The sea views are wonderful and one can get a taste of the real Mexico, plus have access to the state of Oaxaca with its incredible pre-colonial & colonial sites and stunning landscapes and cuisine. Recently there has been an increase in independent local restaurants offering world class food at great prices and with wonderful views. There is a lot of informal tourism in Puerto, with local hotels, rental properties and activities, and the place is popular with Mexicans who want to eat good food and get away from it all.
Maybe one day the world of commercial tourism will catch up and the condo will be worth a fortune, or maybe it'll just stay as it is, either way we win.
