I learned the term "humble luxury" recently; meaning having just the basic things you need in a lovely, calm place, where you can follow the cycles of your life and of the natural world around you. This place is small and basic, but has all the things someone needs for a peaceful holiday in a rural area.
I especially loved how close it is to the beach (2-3 minutes), how quiet and private it feels, and sitting on the patio, watching the hills, birds, sea, and stars.
Maybe some useful notes:
I didn't hire a car and that is very doable, especially in the high season when the buses run more frequently (starting some time in early July through I'm not sure when), but it would depend on what you want to do. I was mostly staying around the apt/beach and taking the bus (about ten minute walk away) into the towns periodically, which that works well for.
The studio and esp the shower are pretty small. It all worked fine for me, traveling solo and not being a large person (for the shower), but as a couple, maybe not great as there are two twin beds instead of one bigger bed; or traveling with a friend, there might not be enough room for personal space without also booking the other studio next door (which seems like it would be a lovely option).
Things are really different in the low vs. high season. In the high, more things are open and open later. In the low, pretty limited options unless you go to town. And the bus runs much less frequently. You would still have no problem getting what you need, but would need to plan more and/or have a car to be happy, probably.
Overall, highly recommended for those looking for a quiet retreat in easy reach of Athens/an international airport, and everything else they might need.
