My husband and I took this trip as a break from our nine month old daughter. We were looking for something that was clean and centrally located with free parking (hard to find in San Francisco) And affordable.
This hotel offers all of that plus an extremely friendly and helpful staff. On the day we checked out, they let us keep our car parked in their lot for four extra hours while we finished up some souveneir shopping. The managers, a husband and wife, were very knowledgeable about San Francisco's districts. They let us know which ones were safe to walk in and which one's were not.
Rather than use our car in the city, the manager recommended we use the muni passport. 18 dollars for a 3 day pass was well worth it! You can buy the pass just three blocks away from the hotel and it allows you access to all city transportation, including the cable cars. The nearest bus stop is just one block away, and that line takes you straight to the waterfront area (one block away front the cable car stop, a few blocks away from pier 39).
Our hotel room was spotless both days we were there (even after we left late our second day and thought they might skip our room.) The refrigerator, microwave and coffee maker looked brand new and worked great! The king bed in our room was comfortable and the bathroom was very roomy. There was no bathtub in our room, but the shower was huge. The hotel complex is closed to the street except for the driveway, so the noise level was nearly nonexistant: we both slept very well.
If your looking for a luxury hotel, this is not it. But, if you're looking for a hotel with a great location, free parking, is clean and is centrally located for a great price (we paid $69 a night), this place is for you.

The Nob Hill motel is a great place to stay right in the heart of San Francisco. It was affordable, clean, and included parking (which, apparently, is a rarity in San Fran). The owners are happy to pull out a map of the city and highlight where to go...and where not to! It's located within walking distance of the Wharf, Union Square, and Downtown, and there are plenty of restaurants and bars to keep ones spirits up. I will definitely be staying with them again. You should too!

It is perfectly located in the centre of SF - you can reach any area of the city really fast. Bus and cable car stops close by. But very quiet!! Free parking, WIFI works. My room was small, which is allright for the price. Only problem: There was a certain bad smell from the sink which I alerted the staff of. Probably some old plumbings. But nothing to get terrified about.

We spent four nights here on a spring vacation getaway. My first impression was that it was clean and decent after booking it from reviews on trip advisor. The price can't be beat --- we paid only $83.00/night for our king room after booking it directly with the motel.
My biggest problem I had was that I kept smelling mold and mildew in the room. I actually saw mold growing on the ceiling in the bathroom. The room looked clean but I couldn't get that mildew smell out of the room. The manager needs a thorough cleaning with bleach! Maybe put in some new vanities in the bathroom!
Hairdryer, shampoo and coffee were all provided in the room with a refrigerator and microwave. Don't expect writing paper or tablet --- couldn't find a single sheet!
Breakfast was apples or bananas, cruissants, danish rolls in paper which was adequate for a light breakfast. There was a great crepe place nearby. Also next door to a Cheese Plus store that had everything we needed such as deli sandwiches, great salads, and more!
We didn't rent a car but had a three day pass for public transporatation such as trolley cars, cable cars, buses, etc. It worked out great and would do it again.
Also, don't get in too late for checking in or call ahead because the desk closes at 11:00. Good thing I called ahead or they would have been closed. Early check outs before 7:00 need to be checked with the manager as well.
A decent, quiet, roomy place to stay and would recommend it more if the mildew smell would disappear!
