I stayed at Donna and Theo's for five days and had a fantastic time. The listing location is perfect if you want a feel for what Brixton offers. Several buses are available for transportation, and the Victoria line is about a 5-minute walk. Also, many shops, restaurants, grocery stores, Brixton Village, Brixton Market, the Ritzy Cinema, and the Black Cultural Archives are minutes away. As for the actual room, it is spacious and clean, with a big bed. Donna keeps a clean and comfortable space. The refrigerator in the room came in handy, as well.
Donna is a gracious host and knowledgeable about Brixton and the happenings in London. She has excellent outing suggestions should you need help. I also had the opportunity to meet Theo briefly; he was very kind. When I return to London, I will stay at Donna and Theo's for sure!
