Regarding The Nafsika Hotel:
George & Costos left the Nafsika about 1-2 years ago, Costas now runs (and has done for the past year) his own cafe/bar called Gravia on the top of the San Stefanos hill, towards Arillas with his brother Yiannis. Very nice place with views over the island of Gravia
George temporarily took over the management of O'Manthas (opposite The Nafsika) in 2009, but I now believe he is back in Sidari.
After suffering the recent sad loss of his mother, Vangelis has also left The Nafsika. He is "doing his own thing" of his passions of fishing and painting. He will be a sad loss, no more "lovely jubbly". He still lives directly behind the Nafsika Hotel.
His place has been taken by a waiter called Spiros (Oh no not another one, the owner was enough), he seems OK but is a bit "stairy"
