We very much liked this apartment. It was bigger than I expected: a nice sized kitchen with plentiful supplies of tea/coffee/salt/pepper etc. Good pots and pans. A nice sized living room with two comfy couches. Good shower in a step-in tub -- lots of towels etc. It's a 2nd floor apartment with quite steep stairs if stairs are an issue.
The neighborhood is Kensal Rise, quiet and a bit out of the center but very reachable by the Underground. The closest station (not very useful) is Kensal Rise, we only used it to get to Gatwick, but the Kensal Green Station (10 minute walk) gets you on the Bakerloo line, which connects to everything. There's a Tesco express close to the station for fruit etc. and a convenience store right on the corner.
Very easy to get in the house and our communication with Amanda was very fast and helpful.
