Lisa was great! Very welcoming and even went out of the way to meet us at the flat very late as my flight arrived at Heathrow around 10 PM. Apartment is cozy but spacious enough for two or three. Not fancy but well furnished, including all the essentials, comfortable bed, nice shower, TV/couch, etc. It's a good base from which to explore London (a 20-30 minute trip to central), but the immediate area is also culturally rich so there's lots to do nearby as well.

PS Brixton Village is awesome if you want delicious and interesting food!
