Looking for a street art tour in Rome at the end of June for myself and my sons--we've done several in London that were the highlights of our trips. I've been searching the internet like crazy, but can't seem to find any tours that are still in operation. I do know about the StreetArtRoma App, but I'd love to have a live walking tour. Thanks!!
Context Travel could probably put one together for you or refer you to someone who does street art in particular.

Do it on a Vespa! Or in an Ape. I saw a film clip with RS doing this and am on the verge of making reservations for myself. I already checked with my travel insurance provider and learned that I'll be covered if there are any problems.
The Street Art tour is the 3rd one described. None of the tours is cheap. This is a link to some of what you might see.
Have you checked Airbnb.com? Besides accommodations they offer "experiences". I booked a water color art class with them in Rome.
Happy travels
