I had this experience years ago. The first place I ever rented in had Wi-Fi that didn’t work and after about a week the water stopped working. I cancelled my booking through support and the owner called me 3 or 4 times on WhatsApp and then left me a bad review. The second place had a shower that didn’t drain and the washing machine flooded the apartment one evening. The third place had black mold growing out of the kitchen ceiling. I tried to get them to waive the cleaning fee over it, but the owner claimed he had told me about it already and refused to do anything. When I left, he told me he had written me a good review and expected one in return. I pointed out that he had done nothing to remedy the mold issue and then posted my own review, and found that in his review he had accused me of bringing prostitutes and drugs into the apartment (which I did not).

It was nominally cheaper to travel this way, but for my next trip I’ll be staying in hotels.
