I will start with what annoyed us so the next travellers are aware of it. There was no "some scaffoldings" around the building. The building was entirely surrounded by them as if they were rebuilding it. The add said "some construction work MIGHT be happening between 9am and 4pm". However, there WAS construction work every but Sunday, it was extremely LOUD and it started at 8am sharp right down the window.
The wooden bed was very noisy too so there was no intimacy at all.
The hosts were kind and answer very quickly to the messages. The instructions to get to the place were clear. The room was very well decorated and clean. It was well situated regarding the transportation to the city center.
I would recommend the room if there was no construction work at all. I think the hosts could wait for them to end before renting the room again because it's very expensive to find a place in London and you don't expect to pay such money to wake up at 8am with that noise during your holidays.
