Nis is a good way to see Serbia from Sofia
The best part of this tour is seeing another country from Sofia. I thought the guide was great and you have a nice drive through the country where you can take photos and just admire the landscape. In the tour you walk around and see the skull tower and a small concentration camp. Walk down town for about an hour and have a nice lunch. This is worth doing but it's Nis isn't an amazing city so know that going in. I would recommend it totally to someone that has never been to Serbia.
