BOOK IT IF YOU FIND THE DATES! Jean's place is fabulous. I felt really lucky that this was the place the host me during my 1st time in USA.
The room is amazing (comfy bed, easy access to the bathroom, spacious, natural light), the house is beautiful (I loved siting at the balcony for breakfast) and location was great (really easy to move around taking the bus, bart, or renting a bike). The kitchen is super well-equiped. The whole house is extremely clean and well decorated.
But the best part indeed is the host herself. Jean was really generous even before my trip, giving me advice on how to get to her place from San Franciso airport. During my stay she took for a mini-tour in SF, which I loved. Also super helpful in letting me know about the services on the surroundings.
Highly recommended!
