If you are thinking of coming to Chania, staying in the old city center, is a must. This place is fantastic, the design is thoughtful, and while you are in the town and next to a couple of taverns, the place is very quiet at night.
Also, you are in the middle of the shops, restaurants and 4 min walk to the venetian pier. Parking is a little of a crap shoot,. but there is a street that you can drive up to, to get you within 400 ft of the apartment. If you get a small european car, chances are that you can get parking.
