Hi @Joanne343. I have an entire guest suite where I have two bedrooms. I also have a modular sofa in the common area that can be made into a bed, but I do not advertise this fact. Because the strain on resources, the sense of clutter from bedding and extra bags, is not how I like the space to be portrayed.
If someone approaches me directly with regards to bunking down another child or adult.... I can deal with it case by case depending on number of days, whether all adults etc. The couch will never match a bed for comfort, so if I was you, I would be very careful whether your superhost status matters or not.
