Seems your memory is failing too.the 3 in the bedroom were 1 at the bottom of the bed, 1 at the top of the bed and 1 from the side. All 3 were fairly low. The side one was very low.The kitchen and living room were 1 room really, in modern terms open plan. 1 was in front of the sofa, 1 from behind the sofa probably halfway up the wall and 1 in the kitchen looking towards the sofa again probably halfway up the wall. 1 in the loggia at about head height and 1 in the bathroom again at about head height looking towards the shower. Now that only makes 8 I can't remember a 9th one, then again wouldn't swear to it.
