what's "eastern style hotel" and how it differs from "western style hotel"
The main difference I found (mainly with private owned accommodation, not necessarily hotels) is that in "western style" accommodation you will have towels, toiletries, tea/coffee, hair dryer, iron etc (+ all, or at least most, utensils you need if renting apartment/ suite). I recently spent holidays in Poland (we usually stay in apartments, as having small kid we value space...). In Poland, lots of places still don't give you those little things that make your stay more pleasant. They sometimes provide them on request.
I didn't see too much of difference in case of hotels, if anything, 3-4 star hotel in Poland will be slightly better than UK fro example.
