It was excellent to have our own guide and this made it a very personal experience. Our guide was not only knowledgeable, he had first-hand experience of the real roots of hip-hop, was funny and friendly. The places we visited were interesting - the Graffiti Hall of Fame, community gardens etc - and not touristy. We got to see some of the streets and sites of everyday Harlem with an entertaining guide. Two hours was perhaps a little long, but that may have been because it was 90 degrees !
