Herbert’s house is a great place to crash in for a few nights. It is spacious and comfortable. The parking is a little tricky but you can find where to park nearby for free. The neighborhood is safe and there is a store close by and access to public transportation.
The only two observations I can make are: 1. The towels and linen were a tad old; 2. the place has a second room that is also rented. I didn’t know this (I expected to see Herbert, not another traveler). Our “neighbors” were very sweet and we did not have any problem, however, I had preferred to know in advance that we were going to share the place with fellow travelers.
Other than that, it is a very good option if you want to visit SF and Herbert is very attentive.
