Stayed at the Anna Studios in June 2008, the apartments are in a good location at the top of the main road that runs through Skala, (a bit of road noise at night) close to all amenities & only a short stroll to the beach, with many supermarkets close by.
We had a split level studio for 3 people with a bathroom, small kitchen & living area on the ground floor , and a large bedroom on the top floor . The shower was a really good for Greece, we've had some shockers in the past.
Self catering facilities were basic, but fine for making cold snacks anything more adventurous could be a struggle. Maid service is once a week.
Air conditioning was a must, and was reasonably priced.
On departure day we had to vacate our room at 10am !! No courtesy room is available & luggage is left around the side of the building, not a huge problem though are plenty of pool bars with excellent facilities down near the beach
All in all pretty good standard of accomodation for what you expect in Greece
