It sounds like a 'first world' problem, but nonetheless, engaging with the main operators in holiday rental market has become a pain in the derriere.
This year's holiday, in Italy, was booked via Airbnb, and required a 50% deposit 6 months before arrival (December), which the property owner told us "I get paid when you arrive".
And there was an Airbnb 10% 'service fee', for a service that doesn't have a 'Contact us' e-mail address on its home page, and also sees fit to tamper with messages passing between client and customer, e.g., by removing contact details.
So, whilst I am happy to provide rental owners with longer reviews for their own use, on say their own web site, reviews for Airbnb's system are now only a begrudging sentence.
Finally, I presently cannot access my Airbnb account - my 'system' is not recognised, and the automated 'send a code to your phone' process did not work, even after several attempts.
Whether this is more of a relief than an annoyance is a moot point ...
