We missed our first night at the hotel, due to the weather and ferry cancellations, but the staff was able to hold our reservation. To compensate they offered us free breakfast, which I thought was really nice.
It is a bit hard to get to on foot, but it's a beautiful hotel. We had a great experience. The room was clean and seems recently remodeled, and it was very comfortable with a great view from the balcony.
We were happily surprised that there was farmer's market on the next street over all day Saturday, and great restaurants and cafes within walking distance. It was ~30 min walk to the Acropolis. We enjoyed our 1 night stay, and were sad we didn't get to stay longer (darn weather!).
