Very cool cave in Oia, Santorini. Rena provided bottled water, delicious bread, jams, coffee, etc. WiFi only worked well when we went outside the apartment. Rena did caution this apartment requires lots of walking up and down the side of the mountain to reach. She's not kidding. You want to be in good shape if you're staying here. In one day in Oia we climbed the equivalent of 42 floors. This was during Europe's heat wave where it reached 95F or more. Those hot Saharan winds did us in.
