I had used Booking.com for a few travel bookings and generally felt good about the company. Then I booked a two-night stay in Seattle and ended up having to stay only one night instead of two. To cancel the second night I had to go through Booking which had an international number (I'm in the US). She ended up placing me on a 20-minute hold -- no exaggeration, I have the phone bill to prove it. While I was being charged International Fees. She lets me know the second night is cancelled. The day of check-in, I noticed the Booking app was listing the same room for $40 cheaper than I was charged. Then I incurred $40 in International calling charges from my phone company. This was an $80 mistake I will not repeat with them. I will not be using this app or company again, and do not recommend them. Priceline has not steered me wrong yet.
