I have been looking to rent out a room for bitcoin, airbnb style (daily rates). It sorta looks like I can do this on your site, but maybe that's not what it's geared for. Firstly, I need to be able to enter a fractional bitcoin price..
The ability to add pictures, and calendar management would also be very nice. In fact, there's a lot you could do with this.
The calendar management part would bring me into the realm of airbnb, and their major competition 9flats already accepts bitcoin so not territory that I would really be filling any need in the market. I'm hoping people will find it more useful for finding real long term roommates, renters, or purchasers.
And you can add pictures!
