Yesterday, I was checking on the internet
near Athens from where we could go the airport
to pick up family
members that will join us in the end of July. I was not looking for long term stays but I read many people giving advice
for marinas in the islands that can be easily reached by ferry
from Piraeus. I am sure that you will get some advice
here on this line.
Regarding my concern I was thinking in the port of Lavrion but I gave up the idea since our family
comes on a Saturday night and charter
fleets occupy the port during the weekend, so I read. I turned my attention to the marinas near Athens (from Piraeus to Cape Sounio) and found them very expensive (still waiting for some emails) except for Zea Marina which I found reasonable priced. I will probably will stay there for 2 nights!
