I've been an AirBnB host for a few years. I'm in no shape to travel myself, but I enjoy welcoming guests from all over the world - and I've been named SuperHost!
When a friend suggested that I become an AirBnB host, I objected: I have no room to rent... all I have is a captain's bed in my living room. Turns out, that bed has been a useful nest for many who want easy access to the Boston T (a short walk from my door), and an inexpensive place to stay.
I enjoy serving as de facto ambassador for my struggling nation, assuring visitors from Asia, Europe, the Middle East, Africa, and South & Central America that people from the USA can be welcoming and fair.
