Hi everyone- I noticed there were a few posts online asking for information on launderettes in the Argostoli area, I thought I'd help after experiencing the same problems finding one myself during a recent trip to lassi. There's a launderette in Argostoli town, to the side of the Argostoli Municipal Theater. It's on the road up the left hand side of the theatre, as you're looking at the theatre from the front. To get to the theatre, follow the main road along the harbour, and take a left up George Vergoti road, just past the Hotel Tourist. Follow the road up and you'll see the theatre just in front of you. Hope this helps!
