If you are in a budget this is the motel, very convenient location and good price. Room was clean and comfortable, not great but good enough for one night maximum two. Walls are thin, so if you are looking for a peaceful and quiet night maybe is not the best place to stay. Other than that service is good.

We stayed two nights in August. We wanted to stay near Fisherman's Wharf, but did not want to spend an arm and a leg on a hotel. That is what we got here. It's right off Lombard, so lots of traffic, the room and decor were old & a bit shabby, but it was clean. Bed was comfortable enough, the room we had was a smoking room so it smelled heavily of air freshener. It was a pleasant enough stay here - like I said, it was clean, the owner was friendly and the parking was free. Easily walk to Fisherman's Wharf from there. We knew we would spend little time in the room, so we did not want to pay high rates, and this suited.

The motel is well located but the breakfast was really poor, just coffee, juice and greasy snacks. The owner made us feel under control during the breakfast. In particular she didn't allow us to bring two trays in our room with the breakfast, explaining us that she didn't have enough trays for the rest of the motel guests. You can feel the stinginess of the owner noticing the old fashioned furnitures of the room and the shabby aspect of the bad linen, however the room was clean.

There are more expensive hotels, of course, that we couldn't afford, but, for our budget, this had everything we needed: a clean place to shower/sleep in a decent neighborhood. The rooms aren't big, but if you plan to be gone all day it doesn't really matter. It has the basics: TV with local & basic channels, clock radio, iron/ironing board, toiletries, clean towels, good shower, comfortable beds. Only [small] negative: if you're close to the front, and want to sleep with the window open, you can hear the cars going down Lombard St (the only reason I gave sleep quality a "3'), so, if you can, get a room in the back.
It's run by a very nice couple, who are very helpful. They recommended a great bike rental place just a few blocks away (only $20 for the whole day, 24 hours -- meaning, even though they close at 8 pm, if you rent it out in the morning, you don't have to return it until the next morning, same time!) and they also called a cab for us.
Also -- and this was the best part for us -- we had a red-eye back home on the last day (11:15 pm) and, even though check-out time is 11 am, they let us keep our bags (3 carry-ons) in a room behind the office so we could go sight-seeing some more! We came back at 9 pm, collected our bags, and got into the taxi that they had called for us earlier in the day. If you arrive later than you thought, they close the office at 10 pm, but there's a button you can press and they come out and check you in.
We would definitely use the San FranciscoTown House Motel again.
