I had a great stay at Irina's apartment. Unfortunately I didn't met her, but her friendly roommate Gregory was really welcoming. The room was large and for this area in SF really quiet. I would only recommend that the windows should be closed at night, because in the early morning you can hear the ships arriving and departing in the harbor ;) Around this Airbnb are a lot of small cafes and restaurants and of course many sights to see. I would totally recommend to stay here, if you want to wake up in a really exciting part of San Francisco.
