The flat is lovely and the view from our balcony is great, you can see the sea which is also a short walk to Khoum Kapi beach. It's a small bay which is also used by the locals in the morning who come down for a swim which is lovely. It was very quiet during our visit. There is another beach about 25 mins walk away with sun beds/parasols for €6 too if you prefer a more comfortable beach area with shade.
The flat is clean and tidy. Plenty of equipment - fridge, washing machine and a cooker/stove which we didn't get to use. Bed was comfortable. Air con was great and kept the flat very cool. TV does have Netflix availability for those that may want to utilise this facility. We only tended to use when we came back from an evening out :)
There are a few local supermarkets around - it may be worth the owner giving those staying at the flat some of this information just to save a bit of time, although we did use internet (wifi works well) to assist us. There are supermarkets a couple of streets back.
The location of the flat is also very close to local bars and restaurants which, when we went (Sept), are used by the locals too so its a nice feel rather than being too touristy. This may change during the height of the season.
The venetian harbour front is also very close walking distance. The old cobbled streets (touristy) are lovely to walk around.
There was a building next door going through construction work which was a bit noisy the first couple of days but it may have only disturbed us the first /second day. The workers tend to start early but we weren't bothered by it for too long. We were off out exploring for the most part.
We didn't get to meet the owner but emailing the owners through air bnb site was helpful and response was good/quick. They also organised our taxi to and from the apartment which was a big help.
We really enjoyed our time in Chania and hope to visit again.
