Dimitra's place is phenomenal. The views are even more breathtaking than you can see on the photos, even better to be enjoyed from the pool, and the apartment have a really high standard. We have been to a couple of places in Greece but this has topped everything. The kitchen was well equipped with the basics. There are a couple of other apartments but it was super quiet for us, we hardly ever saw anyone else and usually had the pool for ourselves.
Dimitra was very quick to respond to any question we had and sent us a couple of tipps what to do when, such as a Greek wedding or a festival that was happening. Her mother was so kind and baked cake and other Greek specialities for us.
The beach is super close, but we'd recommend a car unless you want to have a 2km walk down to the beach - which shouldn't be too bad if it's not too hot. There are Tavernas all around the apartment within walking distance. Chania is not too far by car (less than an hour) and it's only 15min to the next larger town Kissamos (where you can also find a good supermarket). Don't miss the little villages in between though.
And yes, the beach is just fantastic, but you probably heard about Falassarna from other people. It's paradise.
