One word: Wow!
Where should I start? We didn't meet Anna but met her father, who was one of the most generous and friendly hosts we have ever met. His hospitality is already a good reason to visit.
Then, the house/apartment: beautiful, amazing, even prettier in real life than in the pictures. Very large and spacious, very convenient, and right in the middle of the old town (but in a smaller alley with almost no tourists).

So let's keep it simple: I have only good things to say about this place. If I ever visit Chania again I will certainly want to stay here a second time.

(Just keep in mind that, like everything else in the middle of the old town, you'll have to walk a bit with your luggage, so leave your heavy suitcases at home- which is a good idea anyway..)
