This was a good solution as I started a job in the Mission district of San Francisco to stay while I got started and looked for a more permanent place.
It is a bit noisy as the unit faces the street and the street has many people that you can hear. Also, you can hear the family very easily (especially footsteps) that you share the house with.
I wouldn't highly recommend this place if you are expecting it to be cold as they reset the thermostat in order to save energy and I would often come home or wake up with the unit quite cold. In general, San Francisco doesn't get that cold, but it was uncomfortable in January.
In all, the place is very cute and well decorated and they have done a great job of turning it into a very livable space, complete with some basic necessities like a mini fridge and microwave. If you're looking for a reasonably priced place (for SF) with private entry and responsive and nice hosts, I definitely recommend this place.
