Plan the trip
Hungary lays far away from Poland, we need to cross Czech Republic or Slovakia to reach it. The journey by car or a bus took about 10 hours, but only if you departure from the southern part of Poland. If you don’t like to spend so many hours on the road you can also find some decent flights (http://www.lot.com/pl/pl/) from Polish airports to Budapest. But to get nicest deal you should plan the trip faster. Start to look for the flights couple months ahead, to make sure you won’t miss any discount. Beside with earlier planning you will be able to find cheaper accommodation as well. Fortunately the airport in there is situated close to the center, you only have to take a subway to reach the old town for example.
At the older part of Budapest you will find plenty of monuments in a one, small area. One of the nicest objects is the Fisherman Bastion, amazing example of Romanesque Revival style. The buildings look like some castle from fairy tale! At the top of each towers an observation desk is localized, you can see from there panorama over Danube River. If you like a Baroque architecture you will appreciate the tour around Saint Stephan basilica. Church looks amazing also inside, it is covered with colorful fresco and ornaments. Budapest has one of the biggest parliaments in entire world. The Hungarian one was constructed in the nineteenth century in a Gothic Revival style.
