Sonia let us to check in early and greeted us on arrival.
The District & Circle Underground lines (4 open-air tracks) run directly behind the house. Trains went by frequently from shortly after 5:00 a.m. to well after midnight.
The Property Info said "Some noise from railway at the back of the house but as we have double glazing and shutters this is reduced by 90%." This is scientifically impossible -- 20%-65% noise reduction is more typical. Shutters don't reduce noise. Even with all the windows closed, the noise was loud enough to interrupt conversations and prevent sleep.
The vibrations from the trains were not disclosed. The rumbling was felt periodically throughout the house.
Sonia said repeatedly that she had "never" had noise issues with other guests. Yet she responded to guests' review comments about noise in August 2019, August 2018, November 2019, and December 2022.
We checked out after 3 nights. Sonia declined to refund the remaining 2 nights of our reservation.
