Hi, I am Thereza and have just joined Booking.com We have had 3 bookings so far and we are happy with the way the system works. One question though. Our last guest booked for 3 nights and paid Booking.com but after 2 nights he got invited by friends in the city for dinner and to stay over so he checked out. He said h he loved our place and found it beautiful. My question is, do I refund him for the night he did not stay or not?
