This place should not be listed as a regular accommodation. The Tube trains running underneath make it impossible to get any sleep prior to 1.30 am (try earplugs, but the ground will still shake), and the neighboring room will ensure that you can’t get any sleep after that either.
Rooms share a hallway and an entrance, resulting in plenty of additional noise and light throughout the evening. Windows are also facing the street (lower level) so it is not easy to feel completely safe with kids.
I have done plenty of Airbnb and can cope with pretty much anything, but this was too much. Not acceptable at this price.
