Great space in the heart of the city. The space is relatively small, but Raveevarn clearly put thought into every aspect of the design of the unit. I've stayed in places that were twice as large but still not as functional. The bed was extremely comfortable, there was plenty of storage, the bathroom and kitchen were both clean, modern, and very functional. And Raveevarn stocked the kitchen with coffee, drinks, and a couple of small snacks -- definitely more than I expected.
As other reviewers have mentioned, this unit is in an "up and coming" part of the city, so the neighborhood has an unusual mix of hip coffee shops and restaurants, but also some homeless residents and litter. I never felt unsafe in the neighborhood, and the unit itself is very well separated from the street, so there was never any noise and it felt very secure.
I travel to SF for work regularly, so I've stayed at a lot of AirBnbs, and considering the price, this unit is one of the very best values I've found. Highly recommended!
