In response to Rachael Dickinson.....
I have been to Lourdas 3 times now. Twice with my boyfriend and once on my own..... It is a beautiful place and I am trying to book a holiday to go there next week if there are any late deals still!
There's a bus you can catch from the top of the hill which costs 1euro and it goes to Lourdas beach and to Trepaziki beach. I think it leaves Lourdas beach about 17:00 hrs and gets toTrepaziki beach about 17:15 hrs so you can spend most of the day there. I used to walk down the hill in the morning to either beach and catch the bus back. Both are beautiful beaches. I did not find it expensive.
Spiros taverna does lovely Greek food and they are really friendly. Have a wonderful time. If you are going to hire a car, let me know and I can give you lots of tips on where to visit.
