The +: Very comfortable and well-appointed accommodation, including comfortable bed and nice linens throughout. Spacious and luxurious shower. Fast WiFi. Satellite TV. I loved the private entry via garage code so I didn't have to disturb anyone. Close to BART and lots of food options. Uber/Lyft cars were never more than a couple minutes away. Vibrant neighborhood.
The -: There is definitely a cat urine smell. I'm pretty sure I saw the host disputing this in prior reviews when I booked the place. It's definitely there. I don't have the best sense of smell, so if I smell it, it's there. More concerning: You won't be able to sleep in past 7:45am on any day. It sounds like a herd of elephants walking above and you can occasionally hear some voices.
