We went in August 2015 and it was nice. We spent two days in Sibiu which were really beautiful. When we arrived in Sighisoara, the city was dressed in colors and it was preparing for the festival. I felt like I traveled into the medieval era.
We spent 2 days in Sibiu in December last year and it was wonderful. We even got to see the guys arranging the Christmas tree in Piata Mare. We wish we could stay more. We also got to see Sighisoara, in one day. Great place and amazing to see that there were a lot of people and tourists since it is the only inhabited medieval citadel in Europe.
ASTRA Museum is brilliant! It is a great way to see a place full of history where you can experiment and see how people used to live many years ago. Spent several hours walking around this park with our guide Catalin who answered to all of our questions.
When we took this tour we were glad that we could see ASTRA Museum, as we heard interesting thing about that place. If you take this tour you should definitely visit this open air museum. Money well spent!
