I stayed at this villa in July/August 2013 with 7 other friends.
We had a wonderful time here. The villa is massive, the pool is gorgeous and the outside seating areas are great. They even have surround sound with large speakers around the pool!
We loved Aegina island as it is very authentic, the food was simply wonderful and people are very friendly. The beach is just across the road and there is a wonderful taverna there with exceptionally tasty food.
Christos the owner was very helpful, as was his colleague who met us in town after the short boat trip from Piraeus.
The temple Aphaia is literally a few minutes drive away and is a stunning slice of history for you to enjoy.
I have no hesitation recommending this villa- a wonderful place to stay near the beach.
