House Sitter in Phoenix, Arizona

My wife and I, both college educated holding middle and upper management jobs throughout our careers have since retired, are looking for a home we can house sit during any periods of time indicated in our dates. In fact, we are flexible. We have 2 daughters, son and daughter-in-law living in Phoenix and were looking to spend the winter, visiting them for 3-4 months. We are flexible, no real agenda. We are willing to trade accommodations in lieu of pay.
