The location of Sabrina's place was excellent for my purposes. I did not spend any significant amount of time in the unit and was really only there to sleep. The value and convenience in East Palo Alto are unbeatable.
Cleanliness was an issue at Sabrina's place. The kitchen is stocked with plastic cups and plates. Removing the top cup in the stack revealed that it was utterly filthy, like it had simply been rinsed and then put away. Of course, this could have been from a prior guest but because the home doesn't have a dishwasher Sabrina should have checked the cleanliness of everything.
The bedroom was the next area of concern. The pillowcase AND sheets were visibly bleach stained from cosmetics or other products. There's no way that it wasn't noticed in the changing of the sheets from the prior guest. Additionally, the bathroom was only cursorily cleaned. There were stray hairs galore and the mirror was exceptionally dirty.
With more attention to detail towards cleanliness between guests Sabrina's place can be 5 stars all around.
