The owners of Kep Lodge have commenced monthly doof parties which (I'm told) occasionally run until 6am. We were staying at Jasmine on the other side of the hill and could hear it, albeit quietly thankfully, until 4am the other night.
The sound belts out right across the town as they are high up on the hill. I was advised many guests of both Kep and surrounding accommodation have been left more than a little annoyed with some checking out on the spot.
Check with Kep Lodge on their party schedule before you book any accommodation. Better yet, express your disapproval if you think (like I do) this will spoil Keps' quiet charm. Another Snooky is definitely not needed IMHO.
