Location is perfect. Alyki is a small town, you can find a great fish restaurant and Marina's coffee shop just downstairs, you can find a supermarket(Proton) at just next building, you can just find a perfect beach in front of the house. You do not have to walk more than 50 mt to each of all necessarities.
House is perfect, it is plain and simple, just white walls and white bed, new decorated. Bathroom and room (bed, sheets, kitchenette, towels) is perfectly clean. Terrace is more than perfect, you can just sit and watch town people's life like watching a TV show all day. And evenings you can enjoy sunset just in front of you, behind the other corner of the bay.
Marina (Antonis's sister) is a perfect hostess, she is lovely, helpful, trying to make you happy while your stay. You feel like a friend, not just a customer. Sitting in the mornings or late in the evening at her coffee house with local people and watching passerbys makes you feel Greek.
Just to mention, if you are very noise sensitive people, it can be tricky to stay above two restaurants and a coffee shop. If you just close the terrace door and windows and use air condition at night, you won't notice any noise. But if you do not use air condition as we did , especially in the mornings you may hear the daily preparation noise coming from the restaurants from the open windows :)
It was our second time in Paros. Alyki and especially Antonis's place is a perfect spot to stay. We will absolutely stay there while our next visits.
