Hi, I am new to Airbnb. I would like to list two private rooms in my home, but on the options I can only list one room or an entire apartment. This is difficult when one room becomes reserved and the other is free. Does anyone know how to change these options? Also I would like to charge different prices as one room is bigger. Should I make separate listings? Anyway, if you could advise how best to do this I would be very grateful! Thanks
