We stayed at the Studios 26/6 to 3/7/04.
There was no air conditioning - but as we were upstairs we had a lovely breeze that kept the rooms really cool.
The pool was lovely and clean and there was an extensive menu at the poolside restaurant.

We took 2 trips out to Bubble Beach.
We got there by Speedboat which we took from just opposite the Mundail cocktail bar (about 200 metres from Kefalos harbour). 5 euros each (included return trip!)
Hire of the sunbeds is more expensive than Kefalos beach - but it made a change to sunbathe somewhere else!
