I'm a hotelier and the customer service is ok, in the way they can sometimes take a couple of days to get back to you. The extranet has features they should improve such as there isn't a way to cancel deals you create in the promotions tab, you have to ask them to create rooms for you you can't create them yourself in the system. The WORSE part is the review centre, people can post some ridiculous reviews and you can't ask them to be checked/removed, nor you can do a management response like on tripadvisor. If they don't do something about it i think i'd be healthier they remove the review section.
Hi there,
Thank you for your feedback and cooperation with Booking.com You can always contact your Account Manager regarding any issues you encounter in the extranet, they can assist you on a different level than through customer service. The guest reviews express the personal opinions of Booking.com customers who filled out a questionnaire after their stay at the hotel, therefore the hotel is not allowed/required to post. The reviews are screened for obscenities and afterwards published to the page. Please let me know if there is anything that I can assist you with.
Regards, Mac
Booking.com Team
