We had an fabulous time staying in this great property. The balcony looked out over the most beautiful view and the sound of the lapping water below was extremely relaxing. The apartment was very stylish, comfortable, clean and perfect for two. Although we didn't meet Andromahi, everything we needed was left for us or communicated to us before arrival. The video's of how to find the apartment were very useful, we had absolutely no problem finding it because if these, though I can imagine it being a bit tricky without them as Oia has many small streets and paths to get lost on.
We would definitely stay again, although personally we would always try to make it outside of the height of the peak season, as I can imagine that a place as beautiful as Oia would become very busy during this time although Andromahi's place would always be a sanctuary from any hustle and bustle!
