There was great communication with the hosts and they assisted throughout the stay and also helped us arrange a taxi back to the airport at the end.
The apartment was clean and big and just as shown on the pictures.
It had everything you need for a nice stay. The kitchen was well equipped too.
The beds had quality linen and we were provided replacement for them and the towels after the midpoint of our stay.
The A/Cs seemed to work fine but we didn't use them much as our stay was in September.
Wifi worked well throughout the apartment building including the atrium which itself was a very nice spot to hang out at ans relax.
One caveat though: there are several apartments in the building run by the hosts, some are on the ground floor and some are elevated, so if you have a preference, ask to be sure what you're getting.
The location was simply perfect:
10 minutes to the old city center with the restaurants
5 minutes to the rather nice city beach.
5 minutes to the big chain grocery store "Sklavenitis" and literally surrounded by small stores, coffee places and bakeries.
If I ever come back to Chania I'll try and book this place again.
