I think this is a lesson learned from host's stand point as mis-match of guest/host with Heather's case. It made me reconsider about selection of the right kind of guests + reviewing / communicating with guests more carefully before confirming the booking. Obviously Heather's needs / what hosts can offer may differ or may never match.
Also the guests may MISUNDERSTAND the concept of Airbnb. Hosts are not professionals like hotels or service apartment. Hosts offer private space so guests can experience real living in a city. Being a tourist, she probably did not even know that I had offered 1/3 of prices of equivalent facilities around the area. The guests said the price is most expensive of her trip - then again the term "expensive" is rather subjective, as most of my guests are saying the best value ever, and almost all left review as such. So hosts around the world do choose guests carefully. I thought I had been gracious enough that I did not ask securities to escort her /family out, when they reported to me that Heather had invited unregistered guests inside the building, which was clearly against the written house rules, due to STRICT BUILDING POLICY.
AS seen in the PHOTO I do not leave any personal stuffs so the room is messy. Most of them are guide books etc, I left for the convenience of guest etc.
