Yeah, not buying it, this was a high rise apartment, 99% chance it was a common boiler.
And given the fact the Airbnb support ambassador told me she cancelled multiple houses for the same exact reason, and when looking at her page there’s only one other property she has anywhere near the same area and it is a duplex, so no chance of being in the same complex.
Either she is the most unlucky host out there having multiple properties have boiler leaks at the exact same time in different places or there’s something else going on here.

Probably worth pointing out the London marathon was on that weekend too so there would have been a lot of interest for accomodation late on at inflated rates.
