Fake hotel websites
If you plan to have a holiday in Spain make sure you book your holidays on legit websites. There are websites that are clones of real hotel websites. They look really legit and sometimes is hard to say they are fake. If the only payment option they accept is bank transfer you should be aware. Because scammers do this to avoid chargebacks from credit cards. Don't book anything if it looks too good to be true. Always try to find if the hotel exists and if the website is legit. If this hotel is in booking.com try to book from there. Will be safe for you even if it cost you couple bucks more.
