We stayed at the apartment for a week. It was perfect there and we had a great time. The view is fantastic and there are so many cozy places to sit and relax.
Artemis was a great host with a lot of suggestion to do in the area around. The communication was easy.
Sellia is a small village with 2-3 tavernas. You can easily walk there from the apartment. If you are looking for a more touristic place you can drive (10 minutes) or walk (maybe 60 minutes) to Plakias. There are many restaurants and supermarkets.
The driveway is a little steep for those rental cars but doable. We would definitely recommend this villa!
