Extremely clean--note that four floors walk-up means five in U.S. parlance. Very nice place and terrific location. No air conditioning, so after a hot day, it was a little warm, though only gets Eastern sun. Nice little kitchen for those who need it. Very nice bath facilities. Sort of an S shaped studio. Extremely safe neighborhood and building. In rear, so no street noise from retail. Courtyard building so occasional noise from interior but pretty quiet.
