Hello,
I had my stem cell last November in Kings. your mum will probably be in for three weeks. The staff were great and the room had a TV and Wfi connection.
Things that I found useful:-
Thermos jug for ice, Tena pants,toilet wipes,boiled sweets for actual transplant,cotton sleeping hats.
For the boredom it will depend on how she feels each day..there is a trolley that comes round everyday selling newspapers and magazines. An Internet connection if she uses e mail,FaceTime or Skype.
your mum could write a manual on how to manoeuvre the drip trolley..could never understand why all four wheels wanted to go in different directions!
it is a big emotional roller coaster but with the staff and family your mum will be fine.
