Maid of Sker

There are 9 bells on the ground floor to ring.

Enter the hotel in the main lobby to the right on the reception counter is the first bell.
Across the lobby is the bar, on the bar counter is the second bell.
Go back to the reception desk and to the right is a large vent you can crouch and get through to gain access to the reception kiosk. Here there is a map on the wall with 6 more bells to ring.
Collect the map from the box on the table in reception and head to the Chapel (follow the hallway to the door with a cross) where you can find the last bell and the first cylinder

There is one on the desk on the right when you enter.
There are 6 behind the desk on the right on the wall. These are on a map of the first floor.
There is one on the desk on the left when you enter the lobby with the staircase.
There is one in the chapel where you get the Cerberus cylinder.

I also made a Guide for this Achievement as well. I didn't Understand why U had to find a few, And then look at a Map for the rest of them. made a Walkthrough with ALL THE GROUND FLOOR BELL LOCATIONS. Hope U guys Enjoy this Walkthrough I did, Thanks :)
