W 30th street is not too different from the other streets in the 30s, meaning that it is noisy, dirty, and a bit dodgy to walk around on at night. At its intersection with 8th ave, 30th street feels the glow from Madison Sq. Garden and Penn Station, which means that it is more or less always crowded. There is a lot of traffic on the street because it is near the Holland Tunnel, and so even whilst living on higher floors, you will get the noise from the streets. There is a lot of police around because of the nearby train station and police precinct. It is close to the west side train lines, and within walking distance to Times Sq. Though those are really the biggest benefits I can think of. The rent is high in this area, and although it is possible to find a decent amount of space, it is generally small, crowded, and dark. It's a nice street to use as a walk-through, I wouldn't recommend staying here longer than you have to.
