Hi there
Crete is a large island with two international airports. Chania serves the west and Iraklion, the capital, serves the centre and east of the island. You need to see whether you can get flights to Chania from your local airport if that's where you want to go as not all airports offer this, most fly to Iraklion.
If you do fly to Iraklion, then look at Stalis which has all you need and is just 25 kms from the airport, it has a superb beach, loads to see and do, plenty of bars, shops and restaurants and sits on the main north coast bus routes making it easy to get around.
