The place itself is comfortable and especially convenient for walking to other locations in SOMA (e.g. for a business trip for a company located in SOMA). Jefferson was also very responsive to a problem with entering / exiting the unit due to malfunction with the garage door.
That said the unit is on the small side (~200 sq ft) and doesn't retain heat very well being in the garage. The check in process is also quite complex and very easy to mess up despite the instructions sent beforehand. Possible improvements include having the electronic garage control accessible next to the garage entrance rather than behind a separately locked gate or having the front gate automatically lock upon close. Unfortunately the area, like other parts of downtown San Francisco, also suffers from a major homelessness issue and feels particularly unsafe at night.
I can only recommend staying here if being walking distance to locations in SOMA is the primary concern, otherwise I would strongly suggest staying elsewhere in the city and taking rideshare to get in/out instead.
