Great room+bathroom in a quiet residential neighbourhood in London, although it's located near the New Cross Road which it quite busy. It has a very good connection to the city center by a nearby bus.
Uma and her partner are very nice and welcoming people. The room is very clean and although you're staying in their house, it feels like you have your 'private' area in the house with the room and connected bathroom.
If you're a light sleeper I'd recommend earplugs and maybe a sleeping mask. The 'curtains' are not very darkening. I had both items with me (as I'm a light sleeper) and I slept perfectly :).
