We stayed at the maisonette for a week and had an absolutely fantastic time. We were greeted by Olga the mom of one of the owners and she had made sure that there was a bit of food, fruits and water in the fridge, a really nice welcome. The place is not so big, but for a family of 3-4, it is perfect (at least it was for us).
Both balconies not only have great views to the sea, but also to the hills behind the house.
The location is on one of the marked trekking routes on Andros, so if walking is your thing, this is also a prime location.
Be aware that there is no wifi (yet?), so you will need a mobile subscription that works in Greece if you want to stay connected.
If/when we go back to Batsi, we hope this place will be available again.
