I'll echo what others have already said, being a Warm Showers host has many rewards. Give it a shot and see how it goes for you, make adjustments as needed. In the last year I did a series on Bicycle Travel Etiquette on our blog that focused on hosting and being hosted in Warm Showers situations. You might want to give the posts a read for more ideas on how to know if this will work for you and what you can/should expect.
I think you'll love it!
