Niki greeted us at the house upon arrival, after offering to talk to the taxi driver to make sure we arrived without trouble, and then she showed us around the beautiful house. She messaged quickly back when we had any questions, and was so generous.
The house itself is spacious and comfortable, and has 3 verandas, one of which is this amazing two-level thing with an incredible view of Telendos. The house is right in town and it's easy to walk to cafes, restaurants, groceries, and there are even scooter rental shops everywhere. I doubt it could have been a more ideal location.
As for climbing, there were several awesome areas within a 30 minute walk (door to crag), including Grande Grotta. Less obvious was a stairway just south of the house that goes straight up the hill to Gerakios - Trois Ilots.
