The Abrazo 8 villas are absolutely lovely, around a gorgeous swimming pool (a bit cold in April though). We had very nice breakfasts in the rooms.
We had some trouble getting to Santorin: one boat cancelled, then our boat was two hours late so we arrived at 2:30am. Nonetheless, the transfer arranged by Elpida picked us up at the ferry as planned, and Chris welcomed us very nicely in the middle of the night and put us in our rooms. This was a good surprise after a very long day.
We had a great stay in Santorin, walked from Fira to Oia, which is really worth it. Prices in Santorin are high compared to the other islands and there are many more tourists, but it's worth visiting even shortly. If we had had one more day, we would have taken a boat tour to the island in the middle of the caldeira maybe.
Overall, a lovely place, and I recommend highly Elpida for her help, advice, and enthusiasm both before and during our stay.
