Hi there, I'm writing an email to the accomodation staff of my university, replying to a room offer. I would like to ask if there is more noise at? in? the first floor than at? in? the others, but I don't know what is the preposition to use. My sentence is : I heard that some students complained that there is sometimes more noise at/in the first floor than in the others (...). Btw can I say "noisier" ? Or should a say more noisy ? Thanks for your help !
