I had a wonderful stay. Carol maintains her whole house with a garden in a perfect order, she is very kind and always informs in advance about everything you need to know during the stay, gives helpful advices about housing and transportation in Bay Area, and even lets you know when new guests are coming. Apart from other great things, in this house you can meet people from other countries, Silicon Valley startup founders, you can play Carol's piano or go watching squirrels around the house in the morning.
