One of the best choices we made in Bulgaria was to visit Plovdiv and check out the free Plovdiv tour! I think Plovdiv was one of the most beautiful places I’ve ever been. Adi was a great tour guide, she showed us all of the amazing sights in the old city, it was small so we were able to walk through it all in just a couple of hours. She spoke really good english and answered all of our questions, she was very friendly! I recommend a visit to Plovdiv to anyone visiting Bulgaria and I would definitely recommend the Plovdiv Free Tour.
