We really loved the apartment, it felt like home, we really did not miss anything. The fridge was filled with fruits and wine when we arrived. What more could we wish for. A perfectly working, totally quit airco, and the bed-sofa upstairs on the terras ... the kids still miss the evening time when we spend time there for a game. Also the availability to park on the street was an extra when staying in a town.
If I could make a suggestion, I would try to get some kind of a shed against the sun on the roof terras. That would be the topping on the ice cream. That way you would also be able to enjoy breakfast outside, or any other meal.
For all those visiting Chania, I would definitely recommend your place!
