Sandra Ortiz, Santa Ana My experience: We signed up our small flat in San Francisco with HomeExchange.com in March. It is a second home for us (our regular abode being in Santa Ana) and hence available for non-simultaneous exchanges. Since then, we have had eight guest couples visit there, and we have stayed at three of their lovely homes in Nottingham and Bristol, England, and in Sedona, Arizona, with visits pending for ourselves or our kids in Barcelona, Spain; San Diego; Florida; Nicaragua; Puerto Vallarta, Mexico; and Rome. We are negotiating now for exchanges with people in Paris and Bologna, Venice and Florence in Italy. (continued on next photo) Pictured: The home Sandra Ortiz vacationed in Nottingham, England.
