Airbnb Opportunity in San Diego (Feedback Needed)

[David Lowe]

The opportunity: 
7 bed house in North Park, San Diego. 1 shared bathroom per 2 bedrooms. Large communal kitchen, living room, outdoor lounge area. I want to create a coliving community. 

The questions: 
1). What could I charge per room per night bearing in mind each bedroom shares a bathroom with another bedroom? 
2). There is an opportunity to turn 1 bedroom with its own bathroom into a communal area/extra bathroom for the community. You lose a bedroom but you gain a bathroom in case one of the bathrooms is occupied within the shared arrangement. Keep it as a bedroom or turn it into a lounge? 
3). Who would you market this to?
4). What channels would you use to market this?
