Viktor's apartment in Hayes Valley was super clean, very well stocked, and great central home for a week of business travel in SF. I'd stay here again!
The apartment looked out onto a central court yard, so had great light during the day, but I closed the blinds at night (given you look out into another apartment).
Fantastic location. A lot to do nearby -- easy to get around via foot, uber or public transportation. Amazing coffee (Ritual Roaster) and juice bar across the street, as well as some of SFs best restaurants (Souvla) just blocks away.
