Airport transit hotel Pudong

Hi, We will very late arrived at pudong airport around 1 am and we think we better seek hotel near airport to stay overnight. Do anyone know recomended hotel and within walkaway distance from airport? We search in website that da zhong airport hotel is the nearest one. But we still confused what is different between south building and north building? is it all window room? Can Anyone give us any suggestion to choose the hotel and the room?
