This hotel was the least expensive and closest to my training site, right in the heart of San Francisco, making it perfect for my week-long stay here.
First, the room. The rooms are adequately sized but if you want a big shower, this is not the place for you. However, my room was very clean with a king bed, a nice sized TV, desk, Keurig coffee, mini-fridge and AC. There is some street noise, but I barely noticed it.
The staff is extremely helpful and pleasant, with knowledgeable directions to the hundreds of stores and restaurants that populate the area. The hotel is close to almost anything you could want - I walked to AT&T Park, Chinatown, Westfield and Union Square.
They have a small fitness room with a limited amount of equipment and some free weights and a 3rd floor outdoor track for running/walking. There is no pool or other family friendly amenities so keep that in mind. Otherwise, next time I come back to San Francisco for work or without the kids, I wouldn't hesitate staying here again.
