When we arrived the shower door was broken and the shower floor was covered with sand. Both the shower and toilet drained slowly, which we assumed was a combination of the old pipes they had mentioned and the sand that hadn't been cleaned from previous guests. When we mentioned the broken door, they had a handyman fix it and who indicated to us that we were thought to be to blame.
Both the house rules in the listing and the written copy in the room stated that "reasonable quantities" of toilet paper were acceptable; after the toilet stopped functioning altogether, they pointed to a very long general informational text they had sent the day we arrived, where they included a line that no toilet paper was to be put in the toilet at all.
This clearly has confused other guests as well, as the pipes carried jammed toilet paper all the way underneath the shower drain, flooding it after even brief use. When we apologized for the mixup between their two contradictory sets of rules, we received only escalating rudeness and they abruptly cancelled our reservation, although not before having packed the drains of the small apartment (one window) with what they said was an "extremely toxic product" while we still needed time to pack up and leave. We both got very sick in the days afterward.
