You dont need reviews.
Potidea is a dream of a place :-)
Anyways, you can always order a guide book of halkidiki, from www.ianos.gr and they will send you by post.
If you cant read the site (its only in Greek i think) try www.dol.gr .
Its a press office, but i dont think they sale directly from there.
IF you still find problem, mail me and i will send it to you myself!
Hugs from Greece
