Friends have laid flowers at the home of Joanne Bishop, who died on Saturday from multiple stab wounds.
The 39-year-old was found bleeding and in a critical condition at her home in Brent, Tinkers Bridge, early on Tuesday morning last week.
Sadly she died on Saturday.
Friends say Joanne was a "beautiful empathic soul" who was always happy to help anybody in need.
"She was a lovely friend and will be remembered forever in our hearts until we meet again," they said.
Police have launched a murder investigation and 51-year-old Shane Clarke from Buckingham road in Bletchley has been charged in connection with Joanne's death.
He is due to appear in court in Oxford later this month.
