To Paul King,
Went here in July. There are no tennis courts at or near these apartments. We took tennis rackets in case, but won't bother next time. My first reaction was basic apartments in the middle of nowhere, but after a few days appreciated this. Everyone hires a car, so the pool area is never busy, and if you can put up with basic kitchen and bathroom (who goes on holiday to cook anyway) and are prepared to walk or get taxis to restaurants further afield like Lassi and Argostoli (although there are some in Svoronata varying from 15 to 30 minute walk.) you will love this place. May well be going back next year.
There are no tennis courts at or near these apartments, we took rackets, but weighed cases down for nothing. At first I thought never again, basic apartments and middle of nowhere, but everyone got cars and so the pool and sun beds were never busy, and the quietness suited us at night for sleep. You do need to walk to the local restaurants and everyone seemed to eat around 9 to 10 p.m. so the walk was cooler, or hire a car to go into Lassi or Argostoli. But we are planning to go there again, so that speaks for itself.
Don't be alarmed by the laid back ownere Costos. There is no reception and in our apartment the safe was not attached to the wall, but everything was ok.
