We are just back from a one week stay at Olive Farm. We were a group of 10 adults away to celebrate one of the groups 40th birthday. The villa was perfect for the occasion, it is really 2 villas conjoined with shared patio space. The larger villa consisted of 3 bedrooms, the smaller villa 2 bedrooms and one further twin room in the basement. It really suited our needs and has everything you require. We never hired a car, usually walking down to Agia Marina which took around 15-20mins. A taxi to get back up was around 7€. The actual resort was very quiet due to a combination of Greek Easter and start of season, but found Plantanias a little livelier in the evening( and cost around 10€ to get back to the villa). We made plenty of use of the BBQ for evening meals and the shared patio space was ideal for a group of friends (like us) or for family usage.
I wouldn't hesitate to recommend this villa & hope to be able to return again in the near future.
