The apartment was clean and we had everything we needed there, we could cook (if you are not thinking about French haute cuisine, it should be enough). The bed was comfortable, there is also a washing machine we used several times. The small terrace provides a marvelous view upon the turquoise bay; there we had our breakfast and spent several evenings enjoying the calmness of the night. I had to work one day doing the technical backup for a zoom conference and I can say that Internet worked better than at home, I had zero problems.
As other reviewers pointed out, the house is the last one of Potamos, on the side of Aegiali. Without a car you have to climb a set of stairs that can be challenging in the evening (especially after swimming) and at night (after dinner and having some wine…). We did both, getting a car on our third day and returning it two days before departure, and that was fine for us, there is a parking lot close by and then you walk five to ten minutes until reaching the house. Overall I can say that the feeling of staying on a "nest" up on the hill was worth the walk on the days we didn’t have a car.
I save the best for the end: Lia, the mother of Maria. At arrival she came to pick us up and gave us some basic advice. She stayed on the house next to ours and every time we met, both at home or at the bay, she greeted us with a warm smile (a couple of times with some cake she had baked herself!) giving us tips for restaurants or beaches. Even if I never had bad experiences on airb&b, I don't usually expect my Air B&B host to be that friendly and hospitable: we had the feeling that for Lia we were her private guests, notwithstanding the fact that we had rented the apartment, and that was priceless. For us, Amorgos means the beaches, the sun, the sea - and Lia indeed.
