Michael's place is an excellent quiet hideaway that's still within easy access to a lot of the towns of the Peninsula and bay area. The bed is comfy, there's ample cooking facilities and overall is a great base of operations. I ended up renting a car and parked on the street, so I can't speak to mass transit access, but it looks like it's reasonably close to a bus line and a short drive from the Caltrain station. The communication with Michael was excellent and accommodated my late arrival with ease and was a pretty short drive from SFO (15-20 min).
Overall, if you're looking for a quiet base of operations for the bay area, highly recommend this place!
