Herbert agreed to let us drop off our luggage in the garage in the morning, so we could spend the day in San Francisco. As we travelled in the morning and didn't have an internet connection, we didn't receive the check-in instructions in time. We expected Herbert to live in the upstairs house, but it was in use by other tenants. This caused confusion about our stay, and didn't feel like a warm welcome.
When we returned in the evening for check-in the downstairs entry door by the garage was wide open (luckily the suitcases were still there, nothing taken). In the room we found wet towels on the bed. Contacted Herbert and we had to put clean towels in de dryer by ourselves.
During the first night someone in the main house put on the central air heating of our room (uncomfortable warm), and switched off the power of our (bath)room. During both nights of our stay the people in the main house were noisy between 1 and 3 AM.
The bed is an airbed. The wifi signal is weak in the room. The room itself was nice, with a private bathroom. It took about 45 minutes by public transport to get to downtown SF.
We have never met Herbert in person, though he responded to messages quickly.
