The apartment is beautiful and incredibly comfortable. I ended up staying there for almost 5 months while I was in SF for work.
I would like to note (because it was not shared with me prior to moving in) that there is almost 24/7 construction happening directly outside the apartment. The noise was so loud that I needed to use a fan and white noise machine to even begin to drown it out. It's construction on a large building so I'm guessing it will go on for at least another year or so.
The apartment is smack dab in the middle of the Financial District so it's very convenient for the area and also accessing Muni or Bart. If you're looking for fun nightlife and/or restaurants you'll need to travel outside of FiDi because the neighborhood pretty much shuts down after 6 pm.
The host was mostly responsive though I had a couple communication issues. For instance - before I checked in I asked for the instructions. I didn't hear from her until the day of official check in and then got a very strange email from her dad (?) telling me they were at the apartment waiting for me. I was out of town and not actually checking in until the next day and it was never communicated to me that I needed to be there in person. Also I would often get half responses or very early or late texts regarding various things in the apartment. I also booked for one month increments (had to for work) and was told once by the host that she was "too busy to schedule the cleanings so I should do it myself."
Also the bed in the smaller room is a Murphy bed.
If you can get past those things, this is a wonderful place to stay. It was an incredibly comfortable home.
