Lina's is a great place to crash within easy driving distance of the city. The master room and bathroom is large and comfortable, and the bed is great (bring earplugs if you are a light sleeper, as there are planes flying overhead and the house is on a busy street).
A few things to highlight, just to be aware: (1) there are 4 rooms rented out in this house, so it's very much a guest house experience; (2) one of those "rooms" is made of bookshelves and sheets in the living room - this is not shown in the pictures of the house and was surprising; (3) while there is driveway parking, it can only fit 2 cars and there are 4 guests, so you're probably going to be street parking.
All the guests were nice, Lina is a great host, the kitchen is large, and street parking is easy. I would stay again. Good value for the master bedroom, especially in the SF area.
