This is a lovely house with a 180 degree view of the sea that's hard to surpass. The photos don't capture the view which you can see from most rooms. The house itself is very pleasant and comfortable. It was built relatively recently, so it's got modern amenities and design touches, while still very much retaining the look of a greek house.
The location is great and could be used to visit Paros as well. The ferry to Paros is 12 min away and is really fast and easy to take. You definitely need a car. The roads aren't perfect, but our little Hyundai did great. You don't need an RV unless you plan to go off the main roads on Antiparos.
Groceries are 10 min away. Restaurants on Antiparos are average or below (you'll find much better in Paros), but some offer very nice environments.
Overall a beautiful stay. Highly recommend!
