We stayed at the San Remo hotel for 4 nights. Our daughter (1 year) stayed with us. The room was rather small, there is no place for an extra bed for the baby, she slept in the same bed as we did. There was no private bathroom or toilet, but it was very clean.

My daughter recommended this hotel, having stayed here herself.
On arrival, we struggled up the stairs with our heavy cases to the reception. (no lift)
The staff were friendly and showed us to the room- very quaint and oldy-worldy with no room to swing a cat! But hey it was a stones throw from fishermans wharf and for the price, we felt it a bargain! The toilets and showers were shared and along the corridor, but that was not an issue.
We were there 3 nights and enjoyed our time there. It was close to the cable car for down town etc.
Parking could be an issue as they do not have a car park, but for the one night we had the car, we parked in the local supermarket for $16.
I would definately recommend this hotel.

Upon arriving at the hotel i was greeted with a pleasant looking building that was quite charming!
Inside the hotel was extremely rustic and had a funny scent to it.
My room was pretty small in size and only had a sink and the showers/toilets were communal.
The bed wasn't the most comfortable either.
This is all forgiveable given the location and price of the hotel!
It was less than a 5 minute walk to fisherman's Wharf which was fantastic, full of restaurants and sights! The Altatraz ferry was only about a 20 minute walk from here also.
All the local bars offered interesting characters from all over the world and were no more than a 10-15 minute walk away. Columbus avenue offered many beautiful restaurants with a social dine on the street feel and also had a little 'red light district' further from town if that is your scene.
Parking in San Fransisco was a nightmare with 2 hour parking slots free of charge that soon filled up around the hotel, fortunately the hotel offers all night parking for a mere £16 which is by far the cheapest you will find in San Fran and is visible from the hotel!
I doubt that you will find anywhere to stay in San Fransisco that offers better value for money and location than the San Remo!

A friend and I stayed here for an entire week (7th night free) and loved everything about this place. The rooms are small, the beds are great and the people that work here are helpful in every way. We did not mind having the bathroom/showers down the hall (they were kept very clean). It did help that we had a sink in our room (some rooms do not). This hotel is in the North Beach section of town so we ate our way through "Little Italy" all week. Many, many good restaurants within walking distance. The transportation is within a block, inexpensive and easy to use. You do need to be able to climb stairs to get to the rooms. We plan to stay here again and will tell all of our family and friends to give it a try.
