Greek resorts for a beach holiday?

[Firefly45]

Looking for a peaceful, pretty beach resort in Greece or a Greek island. 3 x 50yr old women who aren't looking to party!
Its a minefield.
Any suggestions?

Skala on Kefalonia, pebbly beach so beach shoes are advised, plenty of bars and restaurants but little “night life “ as such. Very friendly, no big/AI resorts. Tesoro Blu is adults only, very smart but a little corporate in feel, Regina del Acqua run by a lovely family. 9 Muses is highly recommended although never stayed there. Resort is a bit hilly. If you’re on FB, have a look at the Skala Kefalonia board, so many people are repeat visitors

Agios Gordios on Corfu. 25 minutes from the airport and a long string of lovely taverns right on the beach for superb evening meals and sunsets
