The studio was made by the main room with a double bed, a fully functioning kitchen, bathroom and a smaller space in the entrance with two more beds. The main room was spacious, tastefully decorated and functional. The smaller entrance space was less spacious and airy, but I slept there and it was fine. The big bonus was the nice large balcony/veranda with a view to the see. Wonderful to have your breakfast or take the sun. Service was first class. Rooms were cleaned every day and Antonis is very helpful and has good advice.
You need your own transport if you wish to move from Kalo Livadi, which is highly recommended as there is so much you may wish to see in the island and in Delos (preferably catch the afternoon boat there, which is not mentioned in the tourist guides, as it is something new).
Only draw back was the afternoon music from the restaurant down the road, but it stops at 10pm (in Saturday at 11), so it did not disturb us too much. All in all then very highly recommended.
