Great location right between the beach and the old town. Very quit at night but a bit noisy in the morning from the school - we didn't mind though. Chania is a great place to stay if you want to combine urban life, historical sights, great cafes and bars with beach and sunbathing.
We really liked the local beach (about five-ten min on feet) The apartment is clean and very modern - seemed like it was kind of upscale compared to general conditions in Crete. And the bed is really good - super nice to have a separate bedroom. The balcony is much bigger than it seems and even though we were there early (april) and some days were windy it still was super pleasant to sit outside. Close to bakery's and shops if you walk toward the Main Street or any cafe/restaurant you could want in the old town or by the beach.
