The water level in the bottle will drop because when ice changes from solid to liquid state, its volume will decrease.

There will be water droplets on the out surface of the bottle. Water vapour from the surrounding air comes into contact with the cold surface of the bottle and condenses, forming water droplets on the outer surface of the bottle.
