"Finding a department (Clinical Investigations) Medical Unit 1. NO MAP"

I am supporting my 84-year-old Mother-in-Law who needs to attend the Clinical Investigations ward in Medical Unit 1. I know where Medical unit 1 is and I have worked out where Clinical investigations are but there is no map online to show how far the unit is from the front entrance - surely in the 21st century there could be an online map to help people - my Mother-in-law is very unwell and not knowing where the unit is has caused her a lot of extra stress.

As there is no online map, I would have thought it would be fairly easy to provide directions and a small printed map showing the location of the appointment.
