People choosing the apartment for its beautiful front terrace should now that the traffic from the highway is incredibly noisy outside. But as long as you don’t open a window (which you don’t have to thanks to the efficient AC) it is rather quiet inside. Especially the windowless bedroom is well protected against the outside noise.
A couple of homeless people are camping under the highway right around the corner, but they are generally respectful and unobtrusive. Walking past the rows of tents under the highway towards downtown can be a bit daunting especially at dark, though.
