No I haven't stayed there but when we go with First Choice we some times Pick up and drop off there. I know there's a paved road outside the main gate of the hotel then the beach. It looks alright.I think it has only had a pool for a while as previously there wasn't one as it was beach front.
You can find pictures of the Fanis on Halkidiki.com on the photogalleries, If you click on
polichrono marie at the top , where it says recent pics ,there is a picture of the pool surrounded by Palm trees and other pics of the hotel.
Hope this helps!
Dont forget to visit Hanioti when you visit.
