What a wonderful cave home. We loved our stay there. It was in a smaller town, not as touristy as Fira or Oai. If you rent a car I imagine it might be more difficult to park in peak season. We came in the off-season (November) and it was rare to have a spot in the small lot that is somewhat close to the villa.
The villa is about a 5- minute walk to the bus station, however the main bus station is in Fira, about 10 minutes walk so probably better to do that unless you are going the opposite direction.
There is a supermarket and several good restaurants within a 5-10 minute walk.
They generously brought us breakfast each morning. At first it was all pastries and most had pork in them which most of us don't eat. They were very kind to switch up the items and one morning brought fresh fruit at our request.
The communication was great and they were eager to help with any questions we had.
