Keith and his family stayed at our home for a little less than two weeks, and they were absolutely perfect guests. Kind, considerate, and really nice people, not to mention their completely adorable son. They left the home in great shape (even emptying the trash bins!), and were excellent communicators.
I also suspect they'd be wonderful hosts, should they ever decide to become Airbnb hosts. They are really friendly and easy to talk to. We hope to stay in touch with them.
