Airbnb turistic booking to inmigrate London

Hello everybody; I'm from Chile and with my family we are going to make a 34 days trip to UK, and wanted to book initially an Airbnb home in London, city were we arrive at first. My doubt is if anybody knows about any inmigration problem with an Airbnb reservation, instead a traditional hotel reservation. It is any risk with this kind of reservation with internacional inmigration policies? Thank you for your answers!
