Elif not executing in program

I am writing a simple text-based game for a college course in which I need to be able to move between rooms until the exit criteria are met. The problem I am running into is I can’t get the ELIF statement to work to set my location from the bedroom to the cellar. It keeps it as bedroom. I am not sure what I’m missing here.

rooms = {
    'Great Hall': {'South': 'Bedroom'},
    'Bedroom': {'North': 'Great Hall', 'East': 'Cellar'},
    'Cellar': {'West': 'Bedroom'}
}


location = 'Great Hall'
direction = ""


while direction != exit:
    print("\nYou are in the", location)

    possible_moves = rooms[location].keys()
    print("Possible moves:", *possible_moves)

    direction = input("Which direction do you wish to go? ").strip().capitalize()
    print("You entered:", direction)

    if direction in possible_moves:
        if location == 'Great Hall':
            location = 'Bedroom'

        if location == 'Bedroom':
            if direction == 'North':
                location = 'Great Hall'
            elif direction == 'East':
                location = 'Cellar'

        if location == 'Cellar':
            location = 'Bedroom'

    elif direction is not possible_moves:
        if direction == 'Exit':
            print("Thank you for playing the game.")
            break
        else:
            print('Invalid direction.')

>Solution :

The issue is that when you change location from Bedroom to Cellar you straight away change it back again, if location == 'Cellar' matches, you need to change a couple of your ifs to elif

    if direction in possible_moves:
        if location == 'Great Hall':
            location = 'Bedroom'

        elif location == 'Bedroom': # if -> elif
            if direction == 'North':
                location = 'Great Hall'
            elif direction == 'East':
                location = 'Cellar'

        elif location == 'Cellar': # if -> elif
            location = 'Bedroom'
