My girlfriend and I had the pleasure to be Kostas guests and can proudly say it was a fantastic stay. The house is beautiful, the location is strategic to travel across any of the wonderful beaches of Santorini. Super clean, fresh towels every day and even a large patio if you plan to enjoy the house much more than we did (the time wasn't enough 😂). I suggest to visit the host and his nephew Byron at Perivolos beach where they run a very cool water sports facility. If you aren't in the mood of flying with the parasail (it's pure fun and I really recommend it), they'll still be able to suggest you the most beautiful places to visit and where to taste the best food on the island.
Thanks Kostas and Byron, we're looking forward to come back to Santorini and stay at your house as soon as possible! K&S
