Just thought id add a quick comment on the Erietta studios, as we only arrived back in the U.K on Monday.
We booked our holiday last minute, and didn't have 'named accomodation', so were a bit weary of what to expect, but first choice had assured us it was in a lively area, as we were a younger couple.
When we got to the studios it was a bit of a shock, because arriving late at night, you assume you can just pop to a bar or restuarant, but the only one nearby was shut!
Be prepared to spend LOTS of euros on taxis if you are not hiring a car in Kefalonia, as it seems to be 10 euros everywhere, and the studios are about 10 minutes from Lassi in the car.
Personally we had no problems with Makis, he helped us out frequently, and let us use his phone to contact first choice when a trip they organise 'forgot to pick us up'!
The studios are basic, and it would have been nice to have a few more facilities, as it was supposed to be self catering, however it was clean, and the cleaning is done regularly.
Makis does have some newer accomodation, which has air conditioning, if we ever went back i would definately ask for that, as it gets very hot at night.
The good parts about the studios is the pool and the bar, which are kept immaculate, and we spent a lot of time there.
The problem we feel with the erietta studios is First Choice, not Makis, they are the worst holiday company I have travelled with, and will not do so again. As long as you respect your accom, Makis is not to bad.
