Yes, it is appropriate, and it is wonderful!
I am a home share host, and I have stayed all over the world with home share hosts.
Not only does it make for a richer experience for guests, it all but guarantees that house rules will not be broken. In fact, my permit to host requires me to be present at all times when guests are here. Definitely hassle free and stress free hosting.
Safety issues are taken care of. We are in California too - earthquakes, weather and fires are a reality. Who is better qualified to take care of our guests in one of these situations than we are?
Home share guests are respectful and it is great fun to really share with them!
Definitely go for it, and let us know how you like it.
