We are staying about 4 km from Hollywood Walk of Fame, so it's walkable. But it's better to take the subway one station, and then walk the rest of the way.
Hollywood Walk of Fame is on Hollywood Boulevard, and is lots and lots of stars on the sidewalk on both sides of the boulevard. There is a name of a well known "star" in almost each star, but I saw some without names, and some had names of groups as well. E.g. Bee Gees.
I took photos of some of them. The Chinese Theater, where some well known stars have placed hand and footprints is also located on Hollywood Boulevard.
