Excellent appartment, very clean and newly renovated.
It's very close to tube and bus to main touristic place. It's also very close to Tate Modern, St Paul cathedral, London Eye.
The appartment is just above a pub, so it's a little noisy until 11 PM, but after it's very reasonable. The train passes in front of the window, but we can't here it at all.
This is clearly a nice place and we would probably go there again next time we visit London.
