Communication was easy and the lockbox was easily located with photos. The room itself was clean. The front door key however was difficult and took a few tries to open each time as the door was quiet flimsy. You also had to lock it after you and in the event of a fire would have been difficult to exit quickly. The room itself is the hosts room and he stays on a sofa bed with a partition in the shared living area. I know that this is how some airbnbs are, but I do not feel that this was made clear in the description and we may not have booked it had we known. There was a lock on the outside of the door to the bedroom for when you leave but no lock on the inside. This did not feel safe and had I been a lone female traveller would have felt more comfortable if there was a lock on the inside for when sleeping, and if I couldn't be locked in from the outside. The surrounding area isn't great either so again probably isn't ideal if you were a single female.
In general, if you need just a bed to sleep in for the night it is a cheap stay in London and the room is clean and towels were provided. Otherwise the advert needs to be clearer on the set up and I felt it doesn't meet the basic standards I would expect from an airbnb.
