Solid location, but not a flawless facility
My husband and I just returned from a one night stay here a few days ago. While we would stay here again, we would check other places first. 
Pros- Location
We enjoyed the location because it was not in the middle of Union Square, but was close enough that you could walk there. It's also near Japan Town, so there are a lot of great dining options around. It's near several Muni bus stations, although BART is a bit of a walk away if you are carrying luggage. 
Pros- Quick Check-In and Check-Out
After spending most of the morning driving up from Big Sur, we were happy to get into our room ASAP! Check-in was very quick and our room was ready on time. We requested a late check out for the following day and had no issues with honoring our request. Very hassle free. 
Cons- Weird shower curtain
Yes, I know this sounds petty! Let me explain. The bathtub is claw foot and requires a circular shower curtain. It seems the shower curtain is too big for the tub because it kept sticking to half of my body while showering. A little contact is no big deal, but literally half of my body was enveloped in the curtain for most of my shower. I am not a big person, just under 5'3 and normal weight. I tried to finagle it the curtain to stay put, but the weight kept pulling it down. I've been in other circular showers and have never had this problem.
Cons- Charming decor, but dusty smell. 
The rooms are decorated very charmingly, but while the look is supposed to be Victorian, it shouldn't smell dusty. The smell is not overpowering and would probably go away with opening a window for a few hours, but who has that kind of time while traveling? I think they may use vintage furniture in the decor that contributes to the slight smell. Again, not a terrible issue but definitely not something we expected to encounter.
Cons- First floor room lacked a little privacy
We were placed in a room on the first floor which was fine with us given that we didn't want to have to lug our luggage around more than necessary. The room was spacious with nice sunlight. Something that bothered us was that the blinds covering the windows are a white fabric. At night if we had the light on, we are pretty sure that people on the outside could see our shadows. Also, the shades do fully cover the bottom corner of the window, so someone could see in if they really wanted to. The first floor is up high enough that it is not eye-level on the street, but definitely close enough that people walking by across the street could see. San Fran has its fair share of homeless people, meth heads, pimps, etc. (doesn't matter which neighborhood you're in, it's a problem everywhere in SF) so it was not ideal to have a room close to the street that did not offer complete privacy. We didn't feel unsafe in our room, but we definitely kept lights to a minimum at night when we were in. 
Neutral- Service
San Fran is very laid back and chill, but when in a city that has so many hotels to choose from, service makes all the difference. While we didn't have any bad experiences with staff, we didn't have great experiences either. We weren't greeted with a smile at any point, but on the flipside no one grimaced at us. There was some small talk, but it was pretty artificial. I would rather have someone take a straight professional, no-nonsense approach in greeting us rather than obviously going through their scripted questions. Again, it wasn't over the top or sarcastic, but it didn't feel that welcoming either. I get that working in the service industry is tiring and requires a lot of emotional labor to constantly be "on", but it's a requirement if you are going to work the front desk. 
Overall, I would consider staying here again because of the price, but only after looking elsewhere first.
