Tracy is a gracious host! I enjoyed my time at her condo despite a few issues I would consider minor.
Tracy is very open and easy to have long conversations with, which made me feel more comfortable and at home. She would occasionally bake some sweets for me and my GF that we enjoyed a lot. She also brought home some food for us, like tacos or a coconut once haha, I did appreciate that.
The bed was a bit too soft but I didn't mind. My GF however needs a firm mattress to be comfortable.
The room itself was always clean. There was plenty of closet space for my clothes. Tracy provided towels every week for me and my GF. The bathroom was kept clean, there's nothing specific I could point to as a negative.
A few minor issues I had:
Every few weeks, Tracy's building would have their water shut off for maintenance. This was only an inconvenience once or twice. Tracy would notify us before hand though.
In the summer the room would get hot and we would have to open the window and turn the fan on full. I noticed this at other Airbnbs as well, so it might be the older buildings in the SF Bay.
The ventilation for the laundry room wasn't working so we had to keep the window pen when doing laundry.

I don't hold any of this against Tracy, the building is older and these are issues to expect. They were at most a minor inconvenience, and they didn't bother me much personally.
The price was fair for the first few months for a two person accommodation. My GF had stayed with some friends, and I moved to a cheaper one person accommodation nearby.
Overall, I enjoyed my stay.
