First of all, we had a great time at Akti Kastraki. The daily room service was spectacular and we found the aparthotel tastefully appointed and full of convenient amenities. Athina and her staff were super welcoming and kind to us and our eight month old son. Some things to note about this AirBnB:
Transport: you will absolutely need a car to get here and to get around the island. Google put it at 25 minutes from Naxos Town which was accurate. It was a 2-3 minute drive to local tavernas (try Axiotissa, incredible!) and about 10 minutes from Mikri Vigla. There's a bakery there which is fantastic.
Views: earlier reviews mention issues with the photos of the sea view. Our experience was we had a view of the sea from one of the patios but it didn't line up with the listing photos. This wasn't a huge deal for us as the location and beach were exactly what we were looking for but be mindful that you don't have a sweeping sea view from your room.
Things to do: Simply put, there's not much to do here. You'll need to head to Naxos Town for activities, although there are great beaches and some cool art installations to the south. Apeiranthos, Melanes, and the Potamia villages are all worth the price for a guided hike/tour. If the weather is good and you want to hang out, the beach is beautiful and you can walk to the rock formations at Mikri Vigla.
Thank you to Athina and the crew for having us!
