We stayed at the Magda hotel in Aghia Marina in 2004 when we were there for the Olympics.It's only 5 minutes walk from the ferry and has lovely views out to sea. Magda,the owner , is great and the hotel is very nice and even has shower cubicles (rare in Greece unless it's an expensive hotel). We booked online and had a lovely stay there.

Thanks - i'll have a look at that

We stayed at Anna Studios in Aghia Marina. They were lovely only 8 studios all facing sea. Lovely pool and pool bar too. Kosmar used to do them but they don't do the islands out of Pireus now
