Very very pleasant stay. I think the view from Villa Maria is one of the best in Naxos, you can see an astonishing sunset in a wonderful terrace. You'll have breakfast or dine almost touching the sea.
Orkos, where Villa Maria is, is the best area in Naxos: the most beautiful beaches, not too crowded, wonderful nature, not as commercial and touristic as around the Chora.
Villa Maria is a beautiful and comfortable house where you feel like at home: you can find everything you might need and it's really nice both inside and outside. Everything in the house is clean and works.
Irini, Ada's mum, is a very helpful, friendly, caring and pleasant woman. She wrote a small book full of useful advices and indications about Naxos that is available in the house.
I suggest staying at Villa Maria: you'll feel at home and in constant touch with nature in one of the best places in Greece.
