The old town of Chania is really worth a visit, as it is beautifully kept. I have a few favourite places we always visit when we are there. One of them is a cooperative for Cretan artist, where they have thousands of paintings at more than resonable prices (the price is usually €100, or can be "negotiated" to that price). It is situated in a small basement of a stone house in a back alley in the old town. There are also a couple of really nice restaurants, in buldings dating back to the 17th century with a ton of history. One of them (Tamarind) is in a old Turkish Bath house, and really worth a visit.
