Nana'a apartment is exactly as advertised! It is modern and clean with a very cool shower and bathroom, also the air conditioning and wifi work seamlessly too. She is lovely, and met us close by upon our arrival (after providing meticulous directions) even though we arrived before 7am! To that end, she also arranged a private ride for us to the ferry upon our departure. She was happy to watch our luggage when we got there, until we could check in. The place felt very home-y and like our own. The wAlk to the main area in Fira is 15-20 minutes, with some hills, but overall not bad. There are also ATV rentals within a few minutes walking distance and these are also a good option to get around (30-40 euros/day for the ATV). We felt that the value of staying at Nanas place was well worth the walking distance to Fira, and our organized tours picked us up close to the apartment in Karterados without having to walk into Fira. We would recommend this to anyone planning to stay in Santorini! Nana definitely deserves her title as super host!
