What a great place! We found it pretty much perfect for our family of 4, and hope to return.
The pictures are accurate - it's a smart townhouse villa in classic "white cube" cyclades architecture, very clean and well maintained. The layout is good (2 bedrooms upstairs, open living space downstairs) and the beds and furnishings were comfortable. Ventilation was excellent and every window and patio/balcony door had retractable insect screens and wooden shutters so air conditioning, while present in the bedrooms, was basically unnecessary. Even with multiple gorgeous beaches in walking distance (Logaras, Punda Beach, Piso Livadi,) the private pool was a big hit.
The immediate area (Logaras) is very family friendly without feeling dead, which was nice. (We found Naoussa, by contrast, to be dominated by a rich student/trustafarian party crowd this year.)
We did not have a car and never felt like we needed one - shops and restaurants were also in walking distance, and we had no problem exploring the island using the public buses. (That said, the roads are narrow and usually without shoulders, let alone sidewalks/pavements. We are pretty early birds so it didn't affect us, but I would not have felt comfortable walking at night without lights.) If you are bringing or renting a car, there is parking for one.
Gabi, our host, was very responsive to all questions and cheerfully arranged taxis from the ferry port and to the airport.
