It's a trade-off between convenience and price
. We used Kusadasi Marina (Kusadasi - a Cruising Guide on the World Cruising and Sailing Wiki
) for a number of years. It was the cheapest of the Setur Group marinas
at the time, very safe and the only slight drawback was the 40-minute taxi trip to Izmir airport. It was, however, very well situated for cruising both the N. Aegean, Dodecanese and Cyclades
and the Turkish coast from Istanbul
Since we left, Easyjet now fly regularly to Izmir from Gatwick (twice a week in low season and four times a week in high season).
