Loved this hostel! I went with my sister for 3 nights and it was amazingly clean. The owners and staff are really nice and will help with anything they can, and cleaned our room every morning with new towels. Our room had a big balcony, a mini fridge and a tv that even got english programs. The villa is only a 5 minute walk from the beach, and only a 20 euro cab ride from the port. The landlady even stayed up until 1 am to let us into our room when we had to take the late ferry!
The price is extremely cheap for the quality of the building/bed/location, and the villa even has a pool if the sea is too cold for you! Around the corner is a mini mart and a bakery, and a 5 minute walk to most restaurants,so food was never an issue.
Would recommend this too anyone, whether you're traveling with friends or a partner. Best villa in santorini!
