You should not have any Puja Room in the bedroom. That is considered as inauspicious. But since you have a very limited space, buy a Puja Temple and have curtains or doors for the same. Place Puja room in North East, East or North directions. North East is the best direction.
Please ensure to place Puja temple on a higher elevation and should not be placed on the floor. Make sure your room is clean and clutter-free. Avoid keeping dustbin inside this room as it will bring negativity.
