Thank you Paraskevas and Yannis, wonderful hosts! They sent the address and map, but still it wasn't super clear so they waited for us on the sidewalk to lead us into the apartment. (Tip: In the end it's actually well indicated : the block has a sign under the street name that says "Jasmine studio." ) It is right next to the sea and the byzantine wall, close to everything you want to visit in the harbour but very quiet for a great nights sleep. Do yourself a favour and finish your Chania apartment search here - perfect cozy place that I wish I could live in myself! Communication was very easy and with a smile.
