This is a tiny apt as part of a 4-5 separate apt complex. All are newly built and very nicely decorated and very clean. Host runs the place like a hotel in that there is somebody there to help during business hours and apt has room service daily. Apartment is very functional but there are no closets in case you are staying long and need to put all your clothing's out. There are wall hangers though. Bathroom, sleeping area, kitchenette are nicely designed and very comfortable. Balcony is very nice. It overlooks the sea and yes it has nice sunset views.
Apt is in fact outside Oia but a short 10 min walk to Oia. Closest grocery store, restaurant, car rental are all less than 5 minutes walk but if you walk 10-15 min to the town all the dinning and shopping is there.
Host is SUPER nice and super attentive. On our arrival he personally walked us to the town to show us where to do food shopping, where to buy ferry tickets, rent a car, dine, .... Thank you very much Marku. If you are planning to stay and visit Oia I definitely recommend this place.
