I travel to London often for work, and this has been my favourite Airbnb by far. It's huge - much bigger than it looks in the pictures - and the location was perfect for me, as my office is near Borough Market, just a five-minute walk away. The kitchen/living room and bedroom are especially spacious, and there are two oversized desks in the living area that are great if you need to get some work done.
While the building is just off a relatively busy street, it's set back from the road and accessible through a secure gate. I felt very safe (something I can't always say about Airbnbs in London!) and there was no noise, either.
Just be warned that there's no elevator, so if you do have heavy bags, be prepared to walk up two flights of stairs.
My next trip is coming up in six weeks and I won't hesitate to book this place again. Just hope it's available!
