We are a couple from Romania working temporarily in Sofia. After taking the Free Sofia Tour we decided for the next weekend to take the free Plovdiv tour. Sofia tour was above average but the one in Plovdiv was awesome. I cannot remember our guide but I do remember that it was on the day Bulgaria celebrated it’s national holiday. All in all, what a great time we had and what a view at the end. Priceless. Don’t forget to tip your guide for the awesome work they do.
