Questions & Answers about W hotelu była miękka kołdra, czyste prześcieradło i wygodny materac.
Because the preposition w meaning in normally takes the locative case when it describes location.
- hotel = dictionary form
- w hotelu = in the hotel
So -u is the locative singular ending here.
Polish usually does not use a dummy subject like English there.
English says:
- There was a soft duvet...
Polish simply says:
- Była miękka kołdra...
So the idea of there was / there were is expressed by był / była / było / były plus the rest of the sentence. The word order helps give that existential meaning.
