I'm a product manager living in San Francisco with my wife and 3 year-old daughter. We haven't done a lot of traveling since our daughter was born, but I have lived in several different countries over the years (Philippines, Mexico, Germany), and traveled extensively throughout the world.
As a guest, I am extremely careful and considerate of your home and things. I'm personally a very clean/neat person, and appreciate that in the places I stay. I am also a homeowner myself, and understand the risk that any owner takes when renting out their property. If you have any questions, I'd be happy to answer them.
