Alexandra's father Andre said: "I had to use all of my annual leave to travel to the hospital in Belfast for Alexandra's treatment.
"The whole situation was financially horrible as we were worrying about money for the house, for bills and Christmas. Costs for petrol were very high and we were spending more money on food, as well as £15 per day for the car park.
"She was an absolutely fantastic support and struck up a great relationship with Alexandra, who felt like she could talk to her about anything.
"After being in the hospital for six months, staying in the house made the hard cancer journey so much easier. It was unbelievable. I really hope people out there know how much it meant to us. I wish it had been open from the start.
"It was heaven to eat something normal and to put on the kettle and make myself a cup of coffee. At this time, the simple things really meant so much to me."
