Lourdas Beach - (Beaches on Kefalonia)

Katie S

We are staying as a couple at Lara Hotel at end of August for 2 weeks.  After reading some of the comments I am seriously worried about the trek to the beach.  Both my partner and myself consider ourselves to be fairly fit individuals, early 50's.  How long does the walk to beach take? brochure says 300m? which should take 10mn.  What facilities are on beach? I understand sunbeds, fine are there WC's and showers? How steep is the hill on way up I don't mean to sound negative but sometimes these small issues can really spoil your holiday.
Any recommendations for restaurants, we eat a lot of fish and seafood?
Thank you for any advice.
