My wife and I stayed at Anna's place for part of our honeymoon in Greece and can't get over the view! This place sits near the bottom of the town, right to the cliff's edge which makes for a spectacular view - both of the caldera, and of the town of Imerovigli hanging onto the cliff side! I loved waking up early and watching the sunlight slowly shine through the caldera and illuminate the picturesque blue/white houses in the stillness of the morning! There is a bakery nearby with excellent pastries that I would grab for me and my sleeping wife. :) The location is great - a bit of effort is required to get to and from Hora's house - probably four flights of stairs, but it is worth it. Don't let that deter you, most everything in Santorini requires a labyrinth of staircases through terraced patios to get to your accommodations. It is part of the experience, but something to note if you are physically unable to safely walk the stairs.
Our check-in experience was easy - Anna arranged for a taxi to pick us up from the airport for 25 Euros. The driver found us easily and dropped us off in the square where a gentleman quickly helped us with our luggage and escorted us to the place.
The only slight disappointment was the privacy of our balcony - This unit is adjacent to a unit with a much larger patio - which takes up a bit of the view. No problem if you neighbors are not home - but if they are there, you basically look into their patio area and you're within talking distance. Our neighbors were great - and it wasn't a problem, but if you are really seeking a private space, this may not be the best choice.
The place itself was clean and spacious enough for two. The pool is shared with the other guests, but we had no problem finding some alone time in the evening. (the water was a bit cold - but it was spring). Everything in the apartment was in working order - we had no issues. We really enjoyed staying in Imerovigli as opposed to Fira or Oia. The views were definitely the best in this town as it is the highest part of the caldera rim.
Anna was very communicative and helpful - she also arranged for our taxi to the ferry on our departure. For the price of this place, it was a very good value.
Pro-tip - you cannot drink the water from the tap in Santorini - so bring some bottled water. Anna had some ready for us when we arrived, but you'll need to make sure you have water for the other days. The bakery/market at the top of the cliff has plenty for cheap.
