I booked the room for 1 night for my boyfriend. He only needed a bed to sleep a few hours because he had missed the last bus to Granada. When he arrived in the flat late in the evening, it turned out the room he was supposed to sleep in was already occupied. He therefore found an empty room to sleep in. He was woken up by the owner in the middle of the night to tell him he was staying in a larger room than the one he had booked and that he had to pay 10€ more. This is not normal. He is the one who suffered the inconvenience of not getting a room he booked, but he was still asked to pay more for finding his own solution to the problem.
