John,
as you say they are basic accommadation,they are set in a very quiet area of Arillas.They are kept nice and clean by rhe owners who live next door,they also have a mini market.The nearest pool to you is at the Makris which is another Manos property(though i do not know the size of the pool,it was only built last year),back towards the main road.The sea is about a 10 minute stroll away,where you will find a few places with pools also.Next door to the Kokinos is a taverna.
