When I travel I look for affordability and location, and you get both with 325.
Room 404 was clean, bed is certainly new and comfortable. There is no A/C, this was not a problem for us, we just opened the window for a bit and done deal.
Walls/windows are not soundproof, if your sleep is a bit shallow bring earplugs, not a problem for me either. We were doing so many things during the day we were dragging ourselves to bed.
Location!!! Starbucks, Chipotle, McDonalds, and more fancy/local options in the same block and nearby. Bart stations at about 5 mins walking, steps away from Union Square and China Town.
