Very outdated!!!
After the long drive from LA, I was hoping my room will be nice and comfy where I can just doze off in. The street where this hotel sits on does not scream welcome. It was deserted and not lit too well. Pulling up to the hotel, there were no valet or bellman to greet us. No biggie. So I walked into the front desk to check in. Upon entering the establishment, I noticed how dated this place looks. I then asked if there was parking available and the staff said that there is a valet charge of $28.50 per night with in and out privileges until midnight. I saw that there was street parking right across the street so I asked the staff if it was safe to park there. She mentioned to me that if I was to park on the street, just make sure that there are no items left in the car like bags or anything that looks valuable as there have been reports of break ins. It was late and I just drove about 7 hours so I decided to valet the car and maybe scope things out in the morning to see if it was safe to park on the street. 
After unloading the car and hand the keys over to the valet, I was directed to the elevator just right around the corner from where the front desk was. The elevator can only accommodate 4 passengers and it's a very old type elevator. Remember, there's really nothing modern about this place. Got off the elevator and walked down the hall to our room. Come to find out, it's right next to the alley with the fire escape just right outside. We can literally open up our window and climb out onto the fire escape. Very NYC. The room was tiny and the floor to ceiling mirror behind the headboard kinda crept me out. This whole place gave me the heeby jeebies. I felt really dirty in the room. This is the first time I actually walked around a hotel room with my slippers on. The bath room sink didn't have a lot of counter space. Well, not enough for 2 that is. So I had to put the toiletries bag in the bedroom. One thing I hate is to have the toilet right next to the shower. I don't want to be getting out of the shower only to walk on eggshells so that I don't accidentally bump into the toilet. The bedroom floor was uneven and when you walk, it creeks. There were parts of the floor where it actually dips. Oh, just hope that you don't have any loud neighbors as the walls are paper thin. You can hear the guest walking around upstairs and also the guest right next door. The room didn't have any ac at all. Just a ceiling fan above. Now, I know that SF doesn't get very hot, but if it did, you'd be baking in there. 
As for the neighborhood, don't go out too late at night. There are transients mostly on Franklin where it's poorly lit. So if you need to get to Hayes St., take Gough to get there. Hayes and Gough is pretty much where all of the restaurants are located. It's about a 2-3 block walk from the hotel. There are different varieties to choose from, so that shouldn't be an issue. 
If you come for just the opera or ballet, then I guess the Inn isn't a bad choice. Actually, I think it's the only hotel in the area. But don't expect too much from this place aesthetics wise. As far as amenities, they do have free wifi available (which is pretty slow) and a free continental breakfast from 7-10am. One last tip, if you do decide to park on the street, keep in mind that from 9am - 6pm Monday - Saturday, it's being monitored by parking enforcement. Not sure if they work on holidays. I would think not. Sunday is not enforced so you can park there all day long. So if you park on any of the enforce days, just make sure you move your car before 11am to avoid any tickets. 
One last thing I have to mention is that the staff here are very professional and friendly. I would give them 4 stars for that. I'm sad that this is a Shell timeshare property as I am an owner of. Properties like these are making me regret getting involved in a timeshare.
