It's definitely an interesting story. The author was offering a personal experience that was enjoyable for both the guest and the host. As he said, his guests and he often established a unique connection. On the other hand:
"When I delivered my rent at the beginning of the next month, I found the management company’s office under construction. It's now a hotel. The “loft-style” rooms are now listed on Airbnb for $169 a night."
Is this how airbnb was intended to be used? Isn't the point of a bed and breakfast-style experience the small-scale feel that the author described? Are guests really going to get the same attention/enjoyment out of airbnb if it's more-or-less a run of the mill hotel experience? Also, aren't there different regulations in place for rentals vs. hotels? The property manager may be violating laws as well.
