Clean room in a multi-unit house, centrally located in SF. Straightforward check-in process - you get the code to the house and your room - and an overall no-frills experience. You get a room with a kitchenette; bathroom is shared. There is a small, shared fridge and microwave in the entryway. I stayed for one night on a business trip (just used the place to sleep) and would stay again if on a similar trip.
