Only after booking was I given very specific and careful instructions on how to avoid any interaction with other residents or building security, entering and leaving through the parking garage.
During my stay I felt like a criminal, even though I quickly figured out that this was a pretty normal thing in this particular building, which was known for loud parties and inconsiderate visitors.
What a terrible experience for me as the guest and the people who have to put up with strangers constantly coming and going.
Airbnb is cool when we're talking about a vacation home or occasional rental of your primary residence - not as a clandestine hotel. I'd be willing to bet that most people, homeowners or responsible renters agree with that, Airbnb's growth goals be damned.
