Yostin Andres Mosquera, from Colombia, killed Albert Alfonso and Paul Longworth in their flat in Shepherds Bush in July last year.
He was caught when members of the public noticed blood leaking from the luggage.
Sentencing judge Mr Justice Bennathan says his internet history was also incriminating.
Detective Chief Inspector Ollie Stride, from the Met’s Specialist Crime Command who led this investigation, said:
“This has been one of the most harrowing murders my team and I have ever investigated.
“The team have consumed hundreds of hours of footage – including the murder of Albert Alfonso.
“Those images will stay with all of us for a very long time.
“Paul and Albert were murdered in the most brutal and callous of ways.
“They had known one another for decades and were in a loving, caring relationship.
“They did not deserve to have their lives taken away in the most traumatising of circumstances – in the privacy of their own home, where they had welcomed Mosquera in.
“The couple had opened their door to a man so evil he would take advantage of their lively spirit and generosity, and murder them to satisfy his own financial gains.
“The investigation has been incredibly complex. We have worked tirelessly to secure the trust of those who have been invaluable contributors to our investigation – and build a catalogue of evidence which would ensure we brought Mosquera to justice.
“We are grateful to all those who helped us build this investigation, including Avon and Somerset Police – as well as the many witnesses who provided detailed accounts of events which must have been extremely hard to share. I would also like to thank colleagues from the Crown Prosecution Service and Counsel for their efforts in this case.
“We have also worked closely with the LGBT+ Independent Advisory Group and I am grateful for their support and the advice they have provided as they helped monitor the investigation.
“This is a case which has deeply affected many people from all walks of life – and it has been traumatic for all of my colleagues involved to work on.
“This sentence see justice secured for the cold-blooded murder of two innocent men and taken an evil and dangerous offender off our streets. A sentence of this length demonstrates the seriousness with which the Judge took.
“Our thoughts remain with all those that knew and loved Paul and Albert – and whilst nothing can bring them back, I hope this sentence offers some semblance of justice and closure as you continue to process the trauma of what happened.”
Detective Inspector Neil Meade, from Avon and Somerset Police, said:
“Yostin Mosquera committed truly barbaric crimes which he had clearly planned in advance.
“He has shown a complete lack of remorse for what he did and I’m pleased that Albert and Paul’s family and friends have now seen justice served with this sentence.
“We may never fully know why he took the decision to travel to Bristol and try and dispose of their remains here, but I’m grateful for the support we received from the community and for the work of the investigation team in making sure he was arrested and brought before the courts.”
