We spent 4 nights at Suellen and Davids house. Both were very attentive, they even picked up us at the train stations in our arrival, and made sure we had what we needed.
The listing is as per the description, everything was perfectly clean, and room and bathroom very large and comfortable.
Regarding the neighborhood, our first impression was not good, in the sense that we did not feel safe walking at night from the BART station to the house. However, during the rest of our stay, in the daylight period, we always walked to the station and did not feel that same way. At night we used taxi to go to the house (5usd).
Anyway, we highly recommend anyone to stay there if visiting Berkeley, San Francisco or Oakland.
