We pointed out these problems immediately on arrival. No responses from host at all.
(1) A/c didn't work in very hot weather (40C or 105F).
(2) bathroom not usable since no shower curtain or light ... water spills everywhere and no light or windows to see what's happening.
We paid 1200 euros for 3 nights, and 1 bedroom and 1 bathroom were not usable. Asking for 300 euros refund is reasonable.
