I stayed here for one night with my parents and brother while in SF in May. As it's basically a hotel room with the option of a pull-out sofa bed to accommodate 2 extra guests, the room felt slightly cramped for 4 people (probably perfect for 2 and okay for 3), but we knew what we signed up for when we booked the room for the one night. The room was clean and like the photos suggest, so no complaints there. The location's unbeatable if you want to be based at Union Square, and it's good for exploring the surrounding commercial, touristy areas. Jennifer was very communicative throughout the whole booking process, and our check-in and stay were overall very smooth. Generally it was a good experience, and I'd recommend this to any couple/ party of 2-3 people who want the safe choice of a base at Union Square from which to explore the rest of the city!
