Nothing But A Middleman With No Backbone

If zero stars were possible, zero stars wold be given. When you have problems with unreasonable owners and resort to booking.com as a last resort after trying with an owner multiple times, they just say that they can't do anything about it and give you a meaningless discount. If they're going to just make you deal with the owner anyway, you're much better off using AirBnB or Trivago. Very pointless service with no customer protection, it's basically just a website with a calender at the end of the day.
