Hi James,
The Alexandros are lovely apartments, Angeliki and her husband are there from early morning to late afternoon, cleaning and looking after the gardens etc. They are so peaceful. People say they are quite small but I have to say that for the past few years I have not really experienced staying in a large apartment so the size did not bother me when we stayed last year.
You can also use the pool at the Marvelous a little bit further down the road, this tends to be a little quieter than the Rainbow, but both are really nice and welcoming places to visit.
You must visit the Captains for a meal, great value for money and good quality food. (If you are a fan of an English Breakfast I'm sure they can teach the English how breakfast should be done!) It is a quiet place, with a definite 'greek' feel to it, with good food choices for both Greek & English style food.
Or meander up the road in the morning to the Bakery and get yourself some fresh bread or croissants, and sit on your balcony and enjoy.
We are coming back to Arillas in the last week of September having already visited in May can't wait to get back to all that lovely food and surroundings!
Enjoy.....................
