Mary will give you an insider's look into London which is a ++ if you have no idea where to chart your course. She knows the city in and out and I personally benefitted from her suggestions. She's very helpful and responsive. Brixton is also a little city that's like a movie set and you'll feel a grittier and much more nuanced experience of London. The room was warm and quiet on a rather freezing time to be in England. Value-wise, it's a no brainer.
