I would totally recommend this place if you wanna spend your time in Naxos! It's super nice with family and friends to stay there. The house has a nice interior design, it's clean and woman who takes care about the place is very nice and helpful! You have a great view, opportunity to cook yourself and it's not really touristy as in the main town. It's mostly really quiet and calm (if your neighbors from the big Villa to the right are not having a big party)
The tricky part is the way to the vila mousa. We had to ask several times the way from the port to orkos beach due to the few street signs in Naxos. And make sure that you have no problems with heights. The street to the villa is really steep and its kind of scary because we are not used to this kind of streets. But if you reached the top it's amazing and you won't regret your decision to stay there.
It's really close to a great beach called Mikri Vigla. It's super nice there because of the totally clear blue water, the beachy and rocky area, a very good restaurant and just a few people are there. If you wanna go somewhere I would recommend to rent a car. Naxos is a quite big island and if you are not in fira it's hard to get around.
