We have just returned from two weeks at Delfinia and the views were very good but you are at the bottom of a hill so some means of transport is practical. Go up to Sunnybird and see Tassos, he will give you a good deal on hiring a bike or car. In fact all the car/bike hire staff in Lourdas are very friendly. Delfinia is basic but clean and tidy. Take comfortable shoes if you are walking to the beach as it is a bit of a trek.
