What a fun goal to have a guest property at your house to share your hospitality. Sounds like you have some really great options to choose from in Bali!
I love meeting new people while traveling and it is the main reason why I like staying at hostels so much, because of all the interactions with new people. Maybe I should consider to do this in my life too. I just don't know how I could commit to living in one place for so long to develop a strong following.
