Highly recommend staying Carmen's house if you want to visit SF or silicon valley. Carmen is a warm person, she even invited our kids to play with her children. The location of the house is perfect and it does have a very big kitchen area. All the room and equipment are tidy, clean and new. The house is perfect for the family with 6 to 8 people.
The house is located in the Palo Alto, and it is very close to the Stanford Univ and all the IT companies (HP garage, Facebook, google..). My family and I had a wonderful memory there.
