We enjoyed our stay in Santorini. It was beautiful. With the ferry times, we only had 1 day. We would have liked longer to go to the south of the island to the ancient minoan settlement.
Based on the pictures and time of year, we thought the pool would be open. I don't know the season for the pool, but it is not open mid april.
This was only minor, not sure we would have time to swim for long anyway. The hotel is close to a grocery store (across the street), several restaurants, and a 24hr bakery that makes delicious spankopita. We really enjoyed eating breakfast on our little porch.
