We recently visited St. Petersburg with another couple and booked private tours through Tzarina tours (w/ Nina).  We did 2 days with her and her husband Valentine.  A comfortable van was provided with a great driver (Sergei) who was very professional and made us feel safe to just watch the sights and not worry about traffic, cars, etc.  Valentine took over 500 photos and videos of us enjoying all the sights and shared them with us via WhatsApp.  Nina was a wonderful guide, spoke very good Englis
