Just call the hotels directly, it's safer and you'll receive better rates. I paid to book and hotel and even if everything seemed to work on the Booking.com website, no reservation was ever made due to an internal error@ Booking.com. Customer Care told me they would refund me in 7 to 12 working days... more than 1 month later I still haven't received my money back... Probably I will never get it back. I will just delete my Booking profile and use the website to find hotels that i will call directly instead.
