Yes, please. Instead of "word order" it is more accurate to speak about the order of the Clause Constituents (these can consist of more than one words). The basic Hungarian sentence consists of the following parts: I. the Topic, II. the Focus, III. the Predicate (in most cases a verb), IV. the Coda (tail). It is simple to identify the verb. What comes BEFORE the verb (the Predicate) that is in focus. Let's analyze the your sentences under hese aspects: "A szálloda mögött sétálok": in this sentence the Focus is on "a szálloda mögött", it means not before, not on Trafalgar Square, not elsewhere. "Én sétálok a szálloda mögött" (correct), the focus is on I (not you, not Aunt Emma). If you omit the pronoun "Sétálok a szálloda mögött", the Predicate itself is in focus (i am walking, not running, driving, cycling). "Az autó itt van": the Topic or in this case the Subject is "az autó", the focus is on "itt" (not elsewhere) and then comes the Predicate or verb.
Hungarian does have the same as Turkish, and even more ... szállodaban = in the hotel, szállodaba = into the hotel etc.
In Turkish, what you're asking about would be ...
otelin arkasında = behind the hotel (location) otelin arkasına = (to the place) behind the hotel
In both cases, otel is the same, in its genitive form.
