An old style ferry but comfortable. Could do with a rennovation. Nice restaruant on board. Not too expensive which is a nice change for ferries. Only about 40 minutes late on arrival. Which is good for Greece. Would recommend. A lot cheaper than flying and probably quicker too if you have to go back to Athens.
