This looks like phishing. The message says Booking.com hasn't paid the owners and asks you to transfer money, which is non-refundable. Then they send a code for you to enter on your phone, along with another code they send you. That locks your phone and gives them control, so they can message your contacts pretending to be you, using your name and number. The account receiving the transfer is obviously theirs. Be careful, there are several scams like this online. Use official sites like Booking.com or Trivago, downloaded only from the Play Store. The apartment is listed on Booking.com. Poor owner, someone copied all their information, even the photos.
