Hi Claire,
I have worked in Zakynthos and it is very beautiful !
I just thought i would tell you a little about it !
You can drive around the entire Island in less than 2 hours, the locals are very friendly, but like many small close knit communities they may not be keen on you setting up a business although there are a few brits with businesses there.
Many of the Greek people only live and work there in the summer season and go home to the mainland in winter.........it literally closes down !
Zante town itself has a few places to eat out in the winter, but that is pretty much it !
It really does close down and you have to have worked for a full year to qualify for EKA which when I was there in 05 was 360euros a month, which is enough to live on because there is not much to spend it on...lol !
I have friends on the island and they like the lifestyle of work hard in summer and not work at all in winter.
And expect regular earth tremors !(mini quakes)
Good Luck,
Nance
