So I will start this review with the "bad", which has nothing to do with the host, and the host acknowledges this. The outside of the building does look somewhat dated but that is about all the "bad" with this listing. At no time despite looking dated did we feel unsafe walking outside in the neighborhood. We were met by our host when we arrived (check in is at 2pm which is great). The host gave us a very thorough tour of the property and the home, showing us all the features along with helping us figure our way around the city. The unit pictures do not do it justice. I do need to point out that this is not a kid friendly unit, which for our trip was something my wife and I were looking for.
Both whole foods and trader Joes are a couple of blocks away which made food shopping easy. Union square was also about 10 minutes walk which meant we did not have to have any rented cars, and got by either by public transit, uber/lyft or just plain old walking.
All in all I have to say that this ranks among my top 3 airbnb units that I have had the good fortune of having rented. I highly recommend this unit if you are traveling to SF and looking for a non kid friendly central location
