You get what you pay for.
We needed a room to sleep for two nights and that's what the rooms with two single beds provided. We arrived later than expected but that was no problem. Good communication with Jean! The room and the bathrooms were clean. We even had towels 👍 we slept with open windows and of course we heard the traffic, but what do you expect in middle of London. And of course you hear some other people that live in the other rooms of the flat, but it is much more comfortable than in a big dorm room.
