Dennis' flat is great for solo travelers who are looking to explore. Dennis himself is very friendly, communicative and incredibly knowledgeable about the neighborhood of Brixton specifically and London in general.
I stayed with him for 4 nights and the guest/airbnb room is just as pictured (possibly even better in person). The flat itself is about 2 blocks from the nearest metro and the neighborhood has everything from history, great food options, and beautiful parks all within walking distance. I'd happily stay with Dennis again for a future visit. Cheers!
