Santorini and Naxos Part 2

April 14 - We rented a car from Escape in Naxos for the day, arranged by the hotel (32 euros). We explored some ruins, visited the pottery shop, learned about and bought Kitron, ate a late lunch in Aperathos (look for a restaurant with a view), saw the Statue of Dionysis near Apollonas and the beach, and enjoyed the Eggares Olive Oil Press Museum. We got back in the late afternoon and turned the car keys into the front desk and they contacted the rental agency for us. We made a reservation and used the hotel's jacuzzi and then watched the sunset from the hotel sun deck.
April 15 - Had our last breakfast at Hotel Grotto - best breakfast buffet of the trip! Took the free taxi ride (provided by the hotel) at 10:00 to the airport for our 11:10 flight on Sky Express to Athens. It is about a 40 minute flight. We arrived at the Athens airport, picked up our luggage and found our way to the Metro. Lots of signs to follow and easy to find. The ticket attendant asked if we were seniors and since the answer was yes we, paid 9 euros for both of us into Athens. We changed metro lines at Syntagma square and arrived at the stop for our hotel a few stops later. it was an uneventful ride, with lots of reminders in Greek and English about the upcoming stop and to keep an eye on your belongings.
We checked into the Acropolis Select Hotel and enjoyed a late lunch on the roof top looking at the Acropolis. The next day we did the RS audio walking tour of Athens and then joined our RS tour that evening.
PS - We used the bank cash machine twice in Santorini and never took out cash again. Both car rentals wanted to be paid in cash and we got a discount at our Santorini hotel if we paid in cash. The rest of the time we tapped with our charge card for almost everything. Also Hotel Grotto and Zoe Aegeas each gave us a bottle of local wine - we felt pretty spoiled by the time we left the islands!
