I'd say this is a good beginning. I'd really like to 'pretend' to be a guest and search for my listing (which we can all already do)...
Then go on to 'pretend' to send an enquiry, 'actually' respond to the pretend enquiry as a host, make a 'pretend' payment and booking, 'actually' accept or cancel (in case of instabook) a booking, write reviews for both parties...
There is a LOT of communication that needs to happen between guests and hosts to calibrate expectations correctly and make sure guests are happy. If I could actually see this information exchange happen, I'd be able to improve it.
I understand that 'appearance' will be different on different devices and software, but the _content_ and _timing_ (i.e., which messages are sent on which event) will remain more or less the same.
Thanks.
