Ben's place was a good pit stop for a London visit. It was very clean, well stocked and the check-in and out process was so easy!
The only thing I would mention to keep in mind is that it's a house of multiple Airbnb rooms; which shouldn't be an issue unless (like me) another guest rocks up after midnight, stomps around, has a loud conversation for a few hours and proceeds to use the bathroom at 3am - the waste disposal for the bathroom is very loud.
But I can't fault Ben for this and I think if you're lucky to rent out a few rooms (or have quieter guests) then it'll be pretty good.
