We bought this in hard back as we spend most of the year living in Hungary. It is well set out, readable and a very good reference book. For anyone thinking of visiting this country I'd suggest you get this book as it makes it clear that there is a great deal more to Hungary than Budapest.
I got back from Hungary yesterday after a holiday there with family. I know things change and prices are a little crazy with the GFC worldwide, but the variation in prices and the number of things that have changed in the book that was mid-2009 release (so yes 1 year) leads me to believe that perhaps not as much effort was put into the update of this lonely planet as was needed.
I am a big lonely planet fan, but lately they do not seem to have the same intimate knowledge. My Hungarian inlaws disagreed with many of the recomendations of places to eat/drink, and I have to say that after visiting some places against their advice I am starting to wonder.
LP, please get some locals to re-write/update your Hungary/Budapest books properly!
