This is a lovely light filled flat, comfortable and nice and a great place to stay for one or two people. It was spotless when I arrived. It's in a quiet neighborhood and within easy walking distance to a variety of transport, shopping, restaurants and entertainment.
Felix was a great host, very responsive to all inquiries and provided lots of information about the flat, the neighborhood, transport and the environs beyond. Knowing I love to cook, he went out of his way to send me an email about places to shop for food and wine. They were spot on.
I enjoyed the well appointed kitchen, the lovely views, the personal touches and the wealth of books that helped make me feel like I was home.
Note that this location is just inside the Congestion Zone by about a block or so, so if you're driving, and it's a time when the Congestion Charge is in effect (look that up online), you might want to park outside of the Zone and walk another block or two to avoid the charge.
Next time I'm in London, I will surely look to see if Felix's flat is available.
