croatia holiday apartments

I have to make an international payment to pay off a holiday apartment in Croatia. What is the best way?
I bank with RBS and say they will charge me 20 € and the recipient will be charged upon receipt of payment. As it is only a deposit of £ 100 this seems a little steep. Any advice?
I guess this private reserve, not through an agency. The agencies usually have too many credit cards. I would be wary if a private person applied for a card credit though, cos normally ask you to give them the number on the phone, and it is not wise. Perhaps the owner of the apartment will be the Western Blot Union? http://www.westernunion.co.uk Western Union are able to obtain cash, before the next day and would charge £ 14 to transfer £ 100 to Croatia (I just checked online). That is a burden to you, you pay nothing. That is something less than any SWIFT bank transfer cost. You will receive confirmation when collecting the money, so it can not be cheated. Just check on their website if there is a Western Union agent near the person you are sending the money a. There are quite a few agents in Croatia, although less so in small towns.
