The best location for the guest room is the Northwest direction this corner represents the air element that is considered the most unstable and movable element. Guest bedrooms in this direction will ensure a short and happy stay for guests at home. Another option is the South or Southeast direction.
Avoid the Southwest direction for guests as it is reserved for the master bedroom. Guest will dominate or interfere if the guest bedroom is in the Southwest direction.
The color of the walls can be white, cream, soft pink, or light blue.
South or West is the right direction for placing a bed in the guest room. Place the bed South-North so that guests should sleep with heads towards the South and legs towards the North. There should not be any beam just above the bed. Always keep the bed a little far from the wall for proper air circulation. Avoid placing the bed directly in front of the bathroom door.
Windows in the East and North direction is the right option though it can be in the West also but avoid the South.
All the electric and electronic items should be in the Southeast direction, as it represents the fire element.
The South and West direction is ideal for cabinets and cupboards.
With a little care in the relative positioning and arrangement of the rooms, one could expect to live a peaceful, happy & prosperous life.
