Stayed here for ~5 weeks, really couldn't be a nicer location. The hosts are great and very helpful with recommendations, directions, whatever advice you need.
If you or anyone with you have trouble walking ~10 minutes up or downhill, I'd definitely plan to have a car. if you don't mind the short walk to the beach, it's an awesome chance for some exercise and really stellar views.
There is a sort of "general store" right across the street that is incredibly convenient, with super nice and helpful people running it. The same family has a couple of other shop sand restaurants on the beaches and those are worth checking out too.
Strongly recommend if you stay here that you stop by Pennystella, the restaurant/bar/pool area around the corner on the way to the main beach, very kind family runs it and the food and drinks are great.
Coming from the US driving here was not bad at all. I'd look at one of the rental places nearby the house and pick destinations you want to see. Chania was a straightforward drive and was an incredible place to get to visit.
I'd love to go back sometime! Very strongly recommended.
