Charles is a wonderful host and his flat is absolutely stunning: I've lived in London before and I rarely saw such a nice place. It's classy, clean and comfortable. Check-in procedures are easy and flexible, while the location is superb: close to everything (Clapham Junction gets you everywhere, quickly), but far enough from chaos to be quiet at night -also, some great food and coffee options within walking distance + Clapham Common which is perfect for a morning run! -. Charles himself is super helpful and very easy to get in touch with.
