The house is fantastic: spacious, clean, easy to get to from Chania airport (about 40 mins on a single road). Pool is really incredible at this price and kept our two teenage boys happy for two weeks.
There is a cute beach (pebbly, but sandy and shallow when you are in the sea) around 5 mins walk from the house, with several others less than 15 mins drive away (we recommend Naya Beach Bar). Kissamos with supermarkets, butchers, bars etc is 5 mins drive.
Dimitra (who speaks perfect English) and the owners were very warm and incredibly helpful throughout the stay when we asked for tips (but never intrusive).
There is a main road quite close to the house but we never heard noise from it. You do not have to cross the road to get to the beach and its proximity means that you can travel around the island quickly and easily - which you should do as Crete is stunning.
All in all a fantastic two-week stay - we would strongly recommend Elia Seaside Villa!
