SF-er who ventures out quite often! I'm new to AirBnB, but I'm not new to (website hidden) and staying in other's homes/having travelers in my home.
Thu (Tiffy) and her friends came to our Coop to attend a wedding. Some of her friends arrived in town before she did and I met them at the door welcoming them into the Coop and to all things Santa Cruz. They were very polite and though visibly tired paid close attention to the introductions and to the house rules.
The group had a very tight schedule of events and so I never actually met Tiffy herself. Instead, I had several email communications with her prior to arrival ~ all of which were very pleasant indeed. The group left the house in good shape too!
