Overall, it was a good stay. We stayed for 10 days.
The pool was amazing, we had a nice balcony overseeing the sunrise, the staff was so friendly and helpful, the location was ideal, right in the center of Fira, close to the taxi/bus station, and right next to a bakery/coffee shops for a nice breakfast start of the day.
However, the room was just okay. The double bed was 2 single beds pushed together and were moving a lot. The mattresses were so uncomfortable, only 1 pillow per person. The air conditioning was way too cold, but if you stopped it, it would be way too hot. The air conditioning system was also way too loud, and kept waking us up in the middle of the night. The fridge was leaking and not cold enough to store items in it.
The breakfast provided in the morning was basic, a bit too basic.
There was no ice machine, would need to ask the front desk to get some ice, couple of cubes at a time, making it uncomfortable to ask 4 times a night, even though the front desk staff were ALWAYS helpful and friendly.

First stay in Santorini for us, we liked the hotel, but would probably look for something else whenever we come back to the island.
