Kouros bar is fab, Kostas and Lorna are lovely and very friendly. We go to Sidari every year and have a drink in here every night. It's a short distance out of town, so nice for a quiet drink, but can also get very busy. You are always made welcome.
We go to Sidari every year and stay here. These apts are excellent and George is the best. It's only about a 20min wlak to the centre, so close enough for the nightlife, but also far enough out if you just want a quiet drink. Can experience quiet alot of noice from the apts opposite. Going back this year of course, 7 weeks and counting.
