Less friendly and asked to pay on the spot at check-out, which actually already paid online (how rude as if we were looking for free). After more than 1 hour explaining the proof of online payment, suddenly we are invited to leave the hotel on the grounds that an online payment has been found (short story ... Actually the story is longer in 1 hour). It does not make sense, if indeed the payment has not been made from an online agent to them, why at check-in there is no problem. In fact, it is in question at check-out? Be careful of the traveler, choose the hotel carefully and save all proof of payment.
