I can easily recommend staying at Jen's room for a trip to the bay area. Everything was clean and spacious enough and it served as a great base for getting around quite fast. In addition, there is almost everything you'll need for a stay within a short walk distance (grocery, restaurants, etc.). Also Jen is a really nice person who was easy to get in touch with and who has been available in case you'll need anything. So definitely a recommendation from my side. :)
