Clean. good location (very close to Union Square). some dodgy neighborhoods are only a few blocks away in one direction; I felt safe walking around blocks near the apartment but this is obviously subjective. As prior reviews stated, there is no AC, but this is apparently common in SF given their climate. I’m someone who often can’t sleep without AC on at home and even I slept comfortably during my stay at Kasa with the windows cracked open. Overall no surprises and good value.
