Constantinos Airbnb was one of the best ones I stayed at so far. Everything was just perfect. His mom, Niki was super nice to us. She welcomed us with a delicious homemade meatpie. The next day when we came home we discovered soup on the table which was really yummy as well and for our last day at Kythnos she surprised us with traditional greek cake. She also allowed us to pick some figs from a tree in her backyard. The Airbnb looked really nice from the inside and we also had a little terrace on both sides of it. We felt very comfortable from the moment we got there. The location was pretty good as well, 5Km from the next city and just a 10min walk to the next beach which we basically had to ourselves. I would always stay there again.
