I had a wonderful time at Erika's house. My room and the whole house are very clean, it is a very short walk to the subway station and the best grocery store in the world (Berkeley Bowl) is within walking distance.
With Erika and her sister I even spent one day exploring San Francisco and surrounding area which was great since I wouldn't have been able to go to some of the places without a car.
Erika even gave me some maps of California and some ice pads for my upcoming road trip.
Thanks for everything Erika, and I highly recommend her cute house to anybody who wants to explore San Francisco and the Oakland/Berkeley area.
