We lived In Alex and Lina's apartment for 4 days. At our arrival there had been some "miscommunication", so there we're only prepared for four people and not the five people we had reserved for. The apartment itself we're modern and clean, but didn't fit more than two pr three people comfortably. Note that the apartment is far away (35-40 min) from the center of San Francisco. The apartment is located under the apartment of the owner and it is placed in a basement behind the owner's garage (light is limited). Aside from that Alex was a nice and welcoming host.
