I stayed in Sylvan's place over a weekend and I liked the place really well. The apartment is on the top floor, it's cozy and would work best for a single person or a couple who like to be close :). Sylvan provides all the amenities, there's all you need for cooking and eating as well, and Sylvan is really nice and helpful and eager to make you feel comfortable.
The bathroom has a full-size bathtub and the hot water was good. The main bed was a bit too soft for me, but that's personal of course.
The best way to get to the place with the public transportation is to take the Tube to the Fulham Broadway station (District, the green line, Wimbledon direction from the city center) and then it's a 15-mins walk or bus 211 or 295 (stop: Sherbrooke Road). There are plenty of lovely dining options around, as well as supermarkets, the neighborhood is residential and so it felt nice, tidy and safe.

My only note to someone who might have a light sleep like me: there are planes landing and taking off from Heathrow--those are quite audible, but they stop at night.

All in all I can definitely recommend Sylvan's place.
