Cindy's room has loads of character with that huge book collection and the terrace! The room has all the modern facilities, including internet access, TV, fridge and its own toilette. Location wise, it's 30mins walk to the financial centre, the waterfront and the AT&T centre -I went to a baseball game and the Alcatraz tour and walked to-from the place.
Cindy's recommendations are spot on, I also read about homelessness which is quite obvious in all San Francisco and SoMa is not the exception, but realistically, I had no issues despite walking to many places.
On top of all the above, Cindy was extremely helpful and welcoming, she even invited me to enjoy them for drinks on the Saturday, but I had to give it a miss as I was exhausted after the 11 hour flight and a good walk around the waterfront!
