That view is as gorgeous as on the pictures and even more ! We had a wonderful time in Andromahi's place. The cave house is decorated with great taste. It has a modern touch while keeping the connection with traditions with woods and ironworks. The home made jam are very good !

Has noted in other comments, Oia is very touristic. Thousand of people walk in the main street every day and it is just two stairs above the cave house. However, don't be afraid, people rarely ventured in "our" stair that lead to a dead end. The place is extremely quite even when the whole island rush for sunset. Of course, very few people still pass by the stair. When they do, you can hear them as if they were in the toilet. It was not frequent enough to be an issue though.

Be careful of the wind ! We experienced a very unusual wind blow (a very short one and an other that lasted a night) for the season (early june 2014). The umbrellas has been smashed on the floor and pillows got away. So please, do not take Andromahi's lightly when it comes to bringing back terrace stuff inside in case of strong wind. Some windows are made of a light grid. As a result, the strong wind caused a lot of noise and dust in the cave house. But again, we have been told those wind blows with such a magnitude were unusual.

The only real complain we could have is the bed that could be better.

Overall, we would definitely advise this place to a friend.
