Well it was rather chilly when we went, but I am sure there was air con

Just asked my husband and he said yes.
The layout is............ walk through door, bedroom to left with bed, wardrobe, dressing table, 2 small units and safe.
Next room is bathroom with bath, bidet and toilet.
Then it's the living room/kitchen all in one, with two sofas which can be used as beds. Dining table and chairs, fridge, microwave, sink, cupboards. Balcony with table and 4 chairs, all rooms over look pool.
The is a full size window in the bedroom, but it is high up. I had to stand on tip toes to look out, (I am 5ft 3") Windows are accessible from the walkway, so I kept mine closed.
Your son should be fine in there, you can keep door ajar.
You have a supermarket nearby too.
