The space was wonderful, great for a group, and very walkable both to nearby attractions (London Eye, theatres) and to multiple Tube stops. Nice to be close to central london and yet not in the middle of the tourist rush.
My only hesitation to giving this place five stars is that the host was totally inflexible about us arriving early. We were staying for 8 days for a business trip and had a meeting at 2pm on the first afternoon of our arrival. We hoped to be able to use just one of the bathrooms a little before the 2pm checkin time to freshen up after our transatlantic flight, and the host was unable to accommodate, which was a shame (and very different from other airbnb experiences that I've had). Otherwise, everything was really good.
