Room is as advertised - clean, comfy, quite spacious. Location is excellent if you want to be in Streatham and close to overground trains; was very easy to get into central London and to get to Wimbledon. Great location within Streatham too, close to cafes, groceries, great East African food, and the lovely common + rookery (well worth a visit).
Most importantly, Rebecca is a lovely person and a great host. She did a great job communicating check-in, giving advice and tips, sharing about herself, and being a generous, open, and available host. I had all I needed to have a phenomenal stay, and I'm really glad I chose to stay where I did, given the surplus of AirBnB options in London.
