Have a look at Tripadvisor and see what people have to say. It is a very large country - are you planning to go to the coast - ie Constanza or somewhere or to see Dracula's castle in Transylvania?
I used to go regularly on business - we manufactured garments there - and didn't ilke the country very much. Bucharest was destroyed by Caucescu. He pulled down all the nice buildings and replaced them with some pretty horrible ones.
However I'm sure some parts of Romania are very attractive. Google some of the travel companies who go there and read up about it.
