TLDR: great place/location, phenomenal host, would recommend a sleep mask and ear plugs.
Michael is an excellent host. He promptly responds to messages and goes out of his way to make the place feel more comfortable. During my stay he provided me with a toaster, mattress pad, and desk to work on.
The apartment is small, but perfect for one person and is accurate to the description. The location is in the heart of Hayes Valley, one block away from great restaurants.
The only critique I have is that the walls provide no buffer to the outside world. You can hear people talking on the street outside and can get startled by cars revving or honking. This was particularly annoying at night while trying to fall asleep and on zoom calls. Further, the blinds do a decent job of keeping out light at night, but light still comes in the apartment, which can be slight annoying in the morning.
