i needed a nice quite Greek island for the summer so i was recommended with Sifnos
at first i had Evia at mind ( Limnos _ area )
this summer we don’t want crowds , we just want nice view , nice beach , good food
if you think that there is something better then Sifnos , Please id like some suggestions

Sifnos is an excellent choice.

As a matter of fact if you exclude the jet set islands (Mykonos, Sandorini, Corfu and Rodhes) and the party islands (Ios, Zante) everywhere else is relaxed and easy going.

I left Crete for last since being a very big place, you can have all in one.
