The house is located rather close to Brixton station, a 10-15 minutes' walk or 2 stops by bus. Perfect spot to explore Brixton and the surrounding areas, and very well connected to the rest of London by the Victory Line. The nearby neighborhood of the house is quiet, and the bed is comfy, so I slept perfectly.
The room is nicely decorated, within a quite old house, very well refurbished. The walls and ceilings are relarively thin, so you will hear the other residents of the house, like other guests or the (co)hosts. The room has a private, adjoining bathroom. Important thing about the room to be aware of is the fact, that there's no door between bedroom and bathroom. This is mentioned in the description, but some might read over it.
The description and photos are accurate. I let myself into the house using a key box, and left the house on myself at the last day, met the co-host just once.
Definitely recommended, however, it felt more like a small private hotel, and I'm not sure 100% if this room suits every couple.
