This place is right on a very quiet beach that is good for swimming, snorkeling and fishing.
The place (detached home with gated yard) is quite large. We were traveling as a family of 4 and never felt cramped. Unit even comes with a washing machine. Only downside - no air conditioner. Be sure to close the shutters when the sun comes up and it doesn't get too hot. Also, the evening ocean breezes do a nice job of cooling it down.
Kissamos is less than 5 minute drive and the road to Balos beach (go if you can) is 5 minutes the other direction. Also be sure to visit Bonsai and Art in Trachilos - amazing souvenirs at unbelievable prices.
