STAY HERE! This place was incredible. When you see pictures like this online it's easy to worry that it won't be as good in person, but that is not the case with Emily and Gill's house. The pictures don't do it justice! You are right on the edge of the cliff with unobstructed views of the water and the caldera - incredible sunrise views! It is also very conveniently located - only a minute's walk to the main street in Oia with all the great shops and restaurants, but far enough away (a few stairs below the main street) so that it was quiet and peaceful without a ton of foot traffic right in front of your door.
Emily was great--she made us feel so welcome, and made the check-in process really easy. They arranged a transfer for us from the airport which was nice, and then Emily met us and carried our luggage all the way to the house! We arrived late and really appreciated them meeting us to check in. The also run a REALLY good restaurant only a minute's walk from the house, so we ate there for dinner the night we arrived - try the stuffed peppers, they're incredible! The also delivered fresh bread from the restaurant every morning, which was a really nice touch.
If you're looking for a nice, friendly place to stay for you first time in Greece - this is it!
