"Legend has it that the entrance to the home of Hades, god of the underworld, could be found in a cave at Cape Tainaron, not far from Tainaron Blue Retreat. For a location associated with the underworld, this is a pretty idyllic spot: perfectly positioned at the southernmost point of the Greek mainland, undiscovered by the tourist crowds, boasting spectacular sea views to match any Aegean island (fittingly, it’s also said to have been home to a temple to Poseidon, god of the sea). Housed in a centuries-old tower that was designed to keep intruders out, the fully restored guesthouse now welcomes visitors from around the globe, but not too many of them — there are just three suites, one at the base of the tower, another in its upper section, and a third in the adjoining tower house." - Tablet Hotels
