Check in was seamless. Staff were extremely friendly and helpful. A lady promoting the timeshares was a little pushy but no big deal. Room was very clean (albeit smallish), although furnishings were quite dated (I guess 'quaint' is one way of putting it). The free wifi was acceptable although it was difficult to have a smooth Skype video call, if you need to do that.
The free breakfast had hot food (eggs, waffles) only on the weekend, but there were plenty of healthy calories available (bread, cereal, milk and juice, fresh cut fruit).
The location was near enough to downtown, but not quite walkable (25 minutes through a sketchy area, and some streets were poorly lit) so the bus 5 worked better for us. Short walk to Laguna and Japantown with lots of good eats.
No fitness center. There is only one elevator that is very slow (again, quaint) so you may need to take the stairs on occasion.
Considering that SF is usually massively overpriced for hotel accommodation, this place is excellent value if you are not looking for glamorous furnishings.
