We've stayed at Air BnBs around the world. We've had great experiences and poor ones too. This is - without a doubt - the single best experience we've ever had. Kalliopi is an amazing and accommodating house. The home is charming and well equipped. It's a 10 minute walk from the old port and from the bus station for excursions.
When we arrived late at night, she was there ready for us and whipped up some tasty local food and drink. Totally unnecessary but certainly welcome. From then on, she constantly offered suggestions of what to do and fed us amazing stuff.
We cannot recommend her highly enough. If you want to stay in Chania, stay here. Don't even blink. Just book it now.
