The New York Times had an article a few days ago about a couple that had to wait 2 years to be refunded for a $13,000 payment for two apartments that they booked through Booking.com. It's obviously an extreme example, but I thought it was worth sharing here. At least so that you can be aware and take precautions. Article is unlocked.
In July 2024, a couple used Booking.com to reserve two apartments in Hawaii, but quickly changed their minds. Getting a refund was no day at the beach.
