Congrats on your upcoming trip to Italy! For Rome private tour guides, I highly recommend Agnes Crawford (www.understandingrome.com) as well as Patrizia Sfligiotti ([email protected]). I have done multiple tours with each guide, and every tour continues to surpass the previous one. Most recently, I did a tour of the Jewish Ghetto and Trastevere with Agnes, focusing on medieval art, architecture, and history. One of the best tours I’ve been on.
For tour companies in Rome, I highly recommend Context Travel (www.contexttravel.com). All of their docents (guides) have advanced degrees in art history, architecture history, archaeology, history, and more. Their knowledge helps to dig deeper into Roman history, and I’ve had great experiences on 8 tours so far with Context.
Are you looking to tour any specific sites or areas in Rome and Sorrento? Any additional info can help tailor better to what you’re looking for.
Happy planning!
