This is a great place, exactly as advertised. The bedroom has good cupboard/storage space, dressing table and a comfy bed. The living room is really cute, so is the kitchen.
If you're not into cooking, the area here is full of take out options. There are a lot of grocery shops too, even a big Tesco within walking distance (about 15 min).
The tube stations: Barons Court and West Kensington are just 8-10 min walk away.
The area feels very safe, I was comfortable walking back to the apartment at all times.
I've enjoyed my 6 week stay very much. The host, Luxi (Richard's god-daughter), was very welcoming and helpful. Most of the time I was alone in the apartment, but when Luxi was there I feelt comfortable around her. I even met some family members, who stayed for 1 night, everyone was always respectful of my privacy.
I would gladly come back to Richard's apartment if I'm ever again in the area. It was a great experience.
