This is probably the best Airbnb I've ever stayed in in London. Check in was seamless, the space is as described, the private entrance is so convenient, the bathroom is small (but very functional) and the kitchenette area was thoughtfully laid out.
One thing to note is that the room is at the front of the flat and could be a bit noisy. The street is relatively quiet, but the rubbish pickup happened very early and very loudly one morning and I could hear music coming from somewhere a few times.
All around a perfect place to crash in Brixton!
