Allow me to preface this review by stating not to expect much for the price paid. What you do get is a clean, comfy suite that should have mostly everything you need.
The space is not far from the heart of the city at all (~15-20 minute drive to the Financial District). A bus stop is also within 5 minutes walking distance of the suite.
I can attest to the fact that the walls are ultra thin, so you can expect some noise shared between you and the neighbors. The heating/AC unit added on to the clamor at times.
Overall, I'd say Jean's guest suite is not too shabby. Thank you for a wonderful stay in SF!
