Heirbnb's unit in the heart of Music Row is very close to bars, restaurants, and the Vanderbilt campus. It is a no-frills, good value unit that is a ~25 minute walk or short car ride to downtown.
Unfortunately the street entrance does not lock and the unit itself does not have a swing bar lock (think hotel bar lock that prevents the door from being opened past a certain point) or peephole. As a male traveler with self-defense equipment this still made me uneasy. Do not stay here if you are not comfortable with anyone potentially being in the lobby or outside your door at night.
