The last comment of the person is very WISE. Because my personal experience with three times being in Budapest & Pest & other cities is that, you have big time trouble with the language gap. Nobody seems to be able to help me in the bank, in hostels, at the train office, real-estate agents & clerks, dentists, lawyers and the mobile phone company. Really, I am not kidding here.
I really think, if you want to stay longterm, the first thing you have to do is trying to master the language, otherwise you will be in trouble big time. I myself have put learning the language as my first priority. And I am not even going to stay here longterm.
