Currently, the world is your oyster—or, if necessary, your dialysis machine. And it’s all because of a writer who had a close call with death at a man’s AirBnB.

Famous Argentine penman Hernan Casciari passed away suddenly while staying at Javier Artigas’ house in Montevideo, Uruguay, thanks to AirBnB.

In order to get Casciari to the hospital, Artigas and his wife Alejandra, who worked for the Uruguayan parliament, made arrangements for a police escort.

The pair even gave blood to aid in the treatment of their visitor.

Casciari left Javier and his wife a glowing 5-star rating on AirBnB after being discharged from the hospital and transported home to Argentina, reading:

Excellent lodging for people who are sedentary and at risk for myocardial infarctions. The greatest hospitals are easily accessible from this lovely area.

Without even knowing you, Javier and Alejandra transform into guardian angels who will save your life.

While you are on the verge of passing away, they will drive you directly to the hospital and wait there as the physicians perform a bypass on you.

They offer you books to read and allow you remain at their home for additional nights without charging you since they don’t want you to feel lonely.

Artigas has had medical emergencies when going overseas before. After receiving a kidney illness diagnosis in 2007, he spent years surviving by undergoing many dialysis sessions each week.

For this reason, he developed Connectus, a ground-breaking app that links travelers with kidney disease to hospitals close to their destinations.

Javier’s terrifying journey to Argentina, where no hospital could provide him with dialysis because of his lack of residence, gave birth to the app.

Javier’s life was saved by dialysis when a hospital finally decided to provide it after twelve exhausting hours.

Javier developed the concept for Connectus during his 2,000-kilometer flight home, hoping that no one else would ever experience the stress he did.

Joe Gebbia, the co-founder of AirBnB, was finally provided Casciari’s assessment and information regarding Artigas’s software.

In order to spend time with Artigas and learn more about Casciari’s heart attack, Artigas’s medical experiences, and the app, Gebbia travelled down to Montevideo in 2016.

Gebbia proposed partnering with Artigas in business after hearing his tales.

With the additional financial clout provided by AirBnB, Connectus (now known as ConnectusMedical) has expanded to provide services to over 250,000 people.

The good news doesn’t end there either, as Artigas no longer requires dialysis after receiving a kidney transplant in August 2017, according to the BBC.
