Our stay at Hotel Jason was great. No complaints. The family that owns and operates Hotel Jason are 
wonderful. kind, helpful, accommodating and informative. Mykonos lodging is a little more expensive than many of the islands, but this applies to the entire island, not just one hotel. Our stay was about US$26-28 per person, in late September after the season, so still not a bad deal. Hotel Jason has an adequate sized pool, large poolside patio with chairs and umbrellas, and captures the ambiance of the Greek Islands with buildings of whitewashed finish and blue trim.
Our room was clean and spacious, with an outdoor shaded patio with table and chairs. The patio was surrounded by a garden of fig and other fruit trees and made for a quiet, relaxing place to hang out while back at the room. Hotel Jason is not right in the downtown center of Mykonos (so it is quiet), however it is easy to get to. Being up the hill a bit from town on a two lane curvy road, the bus might be a preference over walking. Their is bus stop located right outside of Hotel Jason, appropriately referred to by the same name. So leaving Mykonos downtown to return, you simply catch the bus to Hotel Jason, only a few minutes away.
Just a short walk down the hill from Hotel Jason – about the equivalent of ” a block” or less, is a little store which has fresh baked pastries filled with feta or spinach in the morning. Add some coffee or tea, figs off the tree, outside the room on the patio, and another great day in Mykonos is on the way.
Returning to Mykonos, it is very likely we would just simply look here first for our next stay.
