This place is exactly as advertised--a room in a house. The room and the house were spotless. The room was comfy and had its own half-bath. Showers are in the larger shared bathroom, and there is limited kitchen use (eat at the table, use the microwave, but you're on vacation! You don't want to cook a five-course meal anyway!). There is an amazingly eclectic collection of books in the room, plus at least one "Little Free Libraries" nearby, which had books I personally liked.
The hosts are super friendly and accommodating, just lovely people. The location was very convenient for us, between the Oakland Airport and Berkeley. The neighborhood was walkable and beautiful.
