Sarah's unit was very clean and pretty spacious for a studio. I wasn''t sent much in the way of access instructions, but it was easy enough to find my way into the unit and get settled once I had the lockbox code. The unit is a private studio built off the garage at the bottom of a house, so there was some amount of noise from foot traffic above and whatnot, but it was actually surprisingly quiet. There was some confusion at checkout (Sarah thought I was checking out the day before my actual checkout date), but it didn't impact my stay. Overall, Sarah's unit was a good option in a quiet part of Potrero Hill.
