We very much enjoyed our stay in Maria's "cave". Although it is like a cave, it has all the modern conveniences you would expect, and dehumidifiers and aircon to ensure un-cave-like conditions. The best thing about it is the location, a short walk uphill from the main car park in Ioulis, and with stunning views of the village above from the door and outside sitting space. Maria was extremely helpful in advance of check-in and during our stay. You should be aware that inside the accommodation there are no windows other than the front door, but this did not bother us because the accommodation is spacious and the village very safe for leaving the door open while you're in the apartment or sitting outside. Ioulis itself is a real jewel of a village, with an amazing labyrinthine topography. Just beware that there are lots of steps and steep inclines everywhere, but the effort is worth it!
