Yes, Booking.com offers a price match guarantee for any accommodations booked on the site. The lower priced reservation needs to be identical in every way — same property and accommodation type, same check-in and check-out dates, and the same cancellation policy. The lower price will not be honored if it is an opaque booking (when the exact property isn’t revealed until the booking is complete), if it’s part of a loyalty or rewards program, or if it’s a special promotion or deal. You have up until 24 hours before your check-in to submit a claim.
