I stayed here for a week in early October while attending a conference at the Moscone Centre. The location is excellent - I walked everywhere all week and it was just a short walk to the Moscone Centre, shopping, Union Square, cable cars, etc. It is particularly close to the BART line, which is extremely convenient if you are flying in - just get the train from the airport and then it's just a couple of minutes walking from the BART station to the hotel (even with lots of bags).
It is true that the hotel's location is on the edge of the seedy part of town, but so are lots of the downtown hotels, including upscale ones like the Hilton, the Parc 55, the Nikko, and one of the Marriotts. It is not a problem as long as you know where you're going when you leave the hotel and don't wander the wrong way into the seedy area! (Always head directly toward the Hallidie Plaza when leaving the hotel (you can see it from the hotel - it's right there) and there you are, in the middle of the shopping/tourist area!) As a woman travelling alone, I stayed there for a week and had no problems, even when arriving back at the hotel after midnight one night, and leaving the hotel (with all my bags) before dawn for an early flight home. Yes, there are homeless people around generally (you will see them if you're anywhere in the downtown area, not just near this hotel), but I never had anyone approach me in the area of the hotel (not even late at night or early in the morning) and I never felt unsafe walking to or from the hotel.
My room was on the 4th floor overlooking Mason St. I could see Nordstrom from my window :-) There was some street noise overnight, but I never really heard any people - just noise from cars and the occasional siren. I had no problems sleeping, but if you are a light sleeper you may want to bring ear plugs.
My room was pleasant and colourful and I had no problems with anything. The free wi-fi worked fine in my room. The TV reception was not great - watchable, but kind of snowy. There were some extra amenities like toothpaste and razors, which were appreciated. Nothing fancy, but it met my needs for the week and I loved the convenient location.
There is a small breakfast buffet available, which is convenient and okay if you get it included with your room, but honestly it's not great and I wouldn't pay extra for it. There are lots of better options in the area for breakfast, if you are paying extra for it. The buffet just had the basics, like coffee, juice, cereal, bread, and some fruit. There were no muffins or pastries and nothing hot, except I think there were some waffles that you could put in the toaster.
The front desk staff was generally very friendly and helpful. I had some issues with my reservations before I arrived (completely my fault) and the staff was very helpful in gettnig everything resolved for me in advance. When I arrived, they helpfully consolidated my two separate reservations for me (so that I didn't need to check-out/in again or change rooms) and even threw in a free breakfast for me.
The only issue I had with the staff was when I was checking out extremely early (before dawn) for my return flight and I first of all had trouble finding the guy who was on duty, then, when I finally found him, he tried to charge me for the free breakfast I had been given when I checked in! I had used the breakfast coupon I had been given when I checked in, so I have no idea why he tried to charge me anyway. I ended up not paying the charge, but it was an unpleasant end to my stay because he was not professional about it at all and left me feeling like a criminal who was cheating him! (That was the only time I saw that guy all week,though - all of the staff for the rest of the week were very good.)
Overall, I was happy with this hotel. The location is great and my room was comfortable.
