Positives. I came for a conference at the Moscone Center and the hotel location is perfect for this. Staff is friendly, contact with people is minimized and that's good for sanitary reasons. Coffee in the room is pretty good - Metropolis. Pretty clean, both room and bathroom. On the checkout day, the locker room is available until late and I was able to sit in the spacious lobby and do work till 9 pm without a problem. Nice soap and shampoo in the room.
On the downside. The room was small, hard to stretch or exercise in the morning. It was kind of smelly inside, but then the building is old and it's probably hard to get rid of the smell unless everything is renovated. I did not feel the smell after a couple of hours inside. Also a bit cold inside. No room service. They don't take out the trash from the room - you have to empty it. This is not a big deal, but it's not possible to recycle as there is only one standard trash can on each floor. The check-in procedure is full of small hoops to jump through (ID, photo, some log-in operations, etc.), but I was still able to do it from the airport on my phone.
