There are few things you can do to more potently deprive people of their dignity and comfort than to neglect their fundamental human needs and disregard the importance of restoring them. Being in a strange place where you don't speak the language and unexpectedly don't have a place to relieve yourself (most significantly at night) was a truly unpleasant experience and the lack of attention or desire to rectify with which we were treated was truly wrong. I would feel ashamed to treat a visitor to my country or home in such a way.
The toilet did not work from the moment we checked in. We notified the host immediately. We went out for the day while an uneducated attempt was made to fix it. It did not work. We notified the host again when we returned that night, and she employed no perceptible sense of urgency and did not tell us the plan until we asked. Nobody showed up to fix it until the next evening, after an entire business day. No explanation for the delay or advice on where to use the bathroom was given. She refused to refund us for a home without a functioning toilet. Even once it was fixed after two days, for the last two days you had to wait several minutes before flushing again.
We were told on check-in that the wifi did not work properly and were given a new piece of hardware to try. The host did not install or test it. The wifi only worked in one room.
The location was exceptional in every way and the home itself was beautiful.
