Suzan is an excellent host - really friendly, helpful and great communication.
The apartment/flat itself is exactly as advertised. It's nothing special for the price, but that's everything in London. In the context of London, it's everything you need, despite being very small and a bit cramped.
It's a fantastic location in terms of the general area, and tube links to Central London and Richmond. However, it is right on a noisy main street, so if you're a light sleeper I would avoid. Suzan does have a bowl of (new and sealed) air buds at the door to help sleep though, which helps!
Overall, the place is good for London, and probably among the best you'd get in this price range. I wouldn't be excited to make it my home, but for a short airbnb stay the pros outweigh the cons.
