I arrived late at night. Instructions to locate the key safe were not great. The area is poorly lit, so finding it was hard and seeing the key codes was impossible without a torch. Key safe is at ankle height, so hard to access without lying on the ground.
Key safe instructions sent with the booking confirmation were wrong. Spent 30 minutes trying, but couldn't get in. Spent the night in sub-zero temperatures walking through London looking for some place safe and warm. Awful experience. Host is refusing to refund the cost.
