It wasn't what I expected.
Stayed 2 nights. Was below my expectation. 
Pro
1. Location-Easy access to downtown and China Town. 5-10 minutes to downtown & China town.
2. Breakfast- Good pastries and black coffee was okay. No cereal, milk, waffles, pancakes or fruits so don't expect too much. Must pay Juices and better coffees (I wonder where they catered this breads..was good)
3. Cleanness- 7.5/10. blanket, pillow case and bed sheet had clean scent. 
4. Check out time- 12pm
5. Hot water- comes out very well.
Con
1. Thin wall-If you stay quite, you can hear next door conversation very well. Luckily, my neighbors were quite people.
2. No air condition-No air condition. It wasn't a big deal to me. Just open the window and let the air flow (but there is no screen though)
3. Heater- This was a major problem that made me really frustrated. When I arrived to the hotel, I had flu symptoms so I turned the heater on, but it did not work (need to turn the nob to turn on-very old heater that you will see from movies) So I called the front desk, but they told me that if I turned the nob, it should work so I should just wait. So I waited about 30 minutes and another 1 hour after making a call to the front desk to let them know that it isn't working still, but again it did not work. Therefore, I went down and spoke to the front desk, but a manager looking guy said they do have central air heating system so it won't turn on unless it hits the set up temperature. They said it will turn on around 1amish so I should just wait. I tried to double confirm his words, but he tried to ignore the subject and gave me extra blankets (has a lots of holes, it felt so gross) to warm myself up. I guess they set up the temperature to 40 or something below... The heater never turned on during the stay. This hotel is not a cheap hotel. It is November, not May or June. They should set up the temperature little higher so it should work when it is needed to the guests. In my opinion they were being such a cheap-skate to save the electric bill. They weren't honest from the beginning. If they told me the truth from the beginning, I would not be upset so much. This issue made me to decide to never come back to this hotel.
4. Room- Please upgrade. At least repaint the walls. Smelled bad the bed wasn't really comfortable (cheap blankets that you can easily see from motels) No hair blow dry in the room nor ironing equipment. Not enough towels, toilet paper and old/cheap looking shower curtain. spotted some stains and scratches on the wall. Near to the restroom window was pretty dirty and many stains. I did not feel good and comfortable at all. 
5. WIFI-free WIFI at the lobby is sooooooooooooooooooooooooo slow.....rooms no have free WIFI. Must pay.
6. Connection problem-90% of the time my phone was "NO SERVICE" so..can you please make the WIFI free in the room?
7. No ice machine.
Location- 8/10
Cleanness-7/10
Service-4/10
Comfort- 3/10
Overall Score- 5.5/10
Recommend for- if you plan out short stays, looking for a place little better than motel in the downtown SF, without free WIFI in the room, want to travel downtown/China town in walking distance and can sleep without the heater during the winter, I recommend this hotel!
Not recommend for-People who is looking for more like hotel, comfortable, clean, free WIFI in the room, need air condition and heater then big no.
