We had booked for a month but because of the lockdown and UK quarantine requirements we left after 2 weeks . For a long term stay , ( or if restaurants are closed so you have to eat every meal in the apartment , the kitchen was very small , no real work surface and no hot water . But for a shorter stay it would be fine .
On the plus side the location is excellent, and it's really quiet at night (except for the squeaky beds), and when we couldn't get the heating to work it was sorted very promptly.
We plan to return to Chania in the spring and would happily book the apartment again .
