We booked a Hotel in Sevilla call Triana Duplex HSH. When we got there first thing we saw was huge cockroache live, even the woman opening the door was completely horrified by it. We wanted to leave but the owner offer to clean and explain that having pest is normal because is a bottom floor and that we should know this is a possibility, and that she would not give a penny back. We wanted to leave of course as it was clear we would be living with pest. Booking.com call us and at the beginning without not even listening to our side pretty much told us we were wrong, and that because the owner had offer a solution (cleaning) and we had rejected it was our problem and they would not do anything about it, after booking.com offered 25 euros on our next booking. I though that all places were supposed to be cleaned already, so clearly the problem is such that cleaning is not enough, and booking.com is not doing anything about it after knowing the situation. No advisement or anything similar on the site. As of today I have not been able to provide a review. We are never using booking.com again, if you have a problem they will not help. Reality is that you can book most places directly and should use tripadvisory for reviews.
