Agree with gerry- lower tower room! Upper tower doesnt have a balcony to chill on and is a little tight, stairs up are a lil sketchy as the railing is a thick metal chain held on with a nail... basically every night we were either bumping our head or knocking the chain off. Lower you have 2 huge day beds to lay out on. 7 is nice if AC is a must. Personally id rather have the wind hollowing through the tower with the sounds of waves crashing against the cliffs... have fun!
