If there is something I could mention about Chania, that is the beautiful beaches and the many places to visit. The beaches of Elafonissi, Balos, Falassarna and Paleochora were the best. Elafonissi is the place to be!
As for the villages, Therissos, Kastelli and again Paleochora...What I only found annoying about Chania was the traffic. It would be great if the local authorities could decrease it and make more parking places.
Despite this, I loved it anyway. Almost anywhere I had dinner, the food was excellent, Cretan cuisine is delicious! Try a dinner at Therissos!
