The self catering chalet that I had booked was double booked on booking. I advised the host at 7pm that I was leaving the national park which is close by and that we would arrive within the hour. I arrived to find that the chalet had been given to three women who claimed to be Eoin, Eoin is a VERY common MAN'S name is Ireland. Anyway the host put us up in a bedroom with two single beds in her house, no private bathroom, but better than sleeping in the car. The host did refund me 60 euro which tbh I think is a bare minimum, considering I had booked a self catering chalet at back of the house.
I would definitely advise you to check with the host that the space hasn't book double booked on booking.
