Romania is really beautiful! It has a lot of natural features, many of which are unique in Europe (volcanic lake, heliothermal lake, delta mouth, etc.)... You need at least 1 week to explore the most important/famous sights. BUT... The infrastructure is really, really crappy...we hardly have any highways, we only have 1 domestic flight (Cluj-Napoca - Bucharest)...one of the main reasons for this is that most of the sights are in the Transylvania region, and the central government doesn't like this region (since it was given to them as a gift after the First World War), and the majority of the population is Hungarian here :) If you are curious about anything related to Romania, I'd be happy to help!
