For a solo traveler Charles’ backyard studio is adequate. It’s about a 15 min walk to the Caltrain and a little further to Safeway. The bed is a twin with a rollout underneath (I did not check this out, but read it in the description) and the bathroom is very small. If you are a larger person, using the toilet may be challenging. Just an FYI. The hosts are rather discreet and I never saw them in the 3 days I was there. Checking in was easy (I checked in about an hour early and they left the key in the lock) and Charles was quick to respond to my queries.
