Hi gareth .... we were over beginning of may , we exchanged some in england just so we had some to hand when we got there .... but did find the exchange rates were better over there , and for once found the rates in Arillas were better than Sidari .... obviously the only drawback is no cash machine now and the rate does change daily , so you do have to plan ahead slightly .....enjoy your stay .
P.s Best rate we found was the travel place to the left of Dimitri's supermarket , and also the Marina hotel although we didnt exchange there so dont know what the commision was like
