Economical and comfortable option
I stayed at this hotel while attending a 5 day conference at the Moscone Center. My employer would only cover a certain amount of money for this stay so I was looking for a close but economical option. There aren't many in this area. I read the reviews on this place and thought I would give it a try. I was not disappointed. 
As other posts indicate, do not expect a doorman, room service or a pool or gym. What you will find, however, is a very nice, clean and friendly place to stay that is most importantly affordable!! The service was prompt and very courteous. Yes, the elevators are old, but they work just fine! The rooms are nothing special but they are super clean and comfortable. My only complaint was that the floors were a little creaky, but that was minor. I was on the 6th floor and it was pretty quiet. The sink in the bathroom was a little small, but it worked just fine. My only complaint would be that the water pressure was not very good. So if that is a dealbreaker for you, don't stay here. But if you're willing to sacrifice a little in this area, you'll find a good deal here. The huge selling point for me was the kitchenette. As I mentioned, I was in town for about 5 days and did not want to spend a lot of money eating out. So I was able to purchase snacks, and most imporantly, large bottles of water to keep in the kitchenette. I made my lunch every day and refilled my water bottles. It was really great! I can see this as a terrific option for families.
Again, don't expect a fancy place. But it's comfortable and in a good location. I was able to walk to the Moscone Center in about 15-20 minutes. The way back is uphill so it's a little more challenging. All in all, I would definitely stay here again. Happy travels!
