you have the wrong link for changing page numbers
try:

https://www.otodom.pl/wynajem/mieszkanie/krakow/?search%5Bdescription%5D=1&search%5Bsubregion_id%5D=410&search%5Bcity_id%5D=38&page=5

as opposed to:

https://www.otodom.pl/wynajem/mieszkanie/krakow/?search%5Bdescription%5D=1&search%5Bsubregion_id%5D=410&search%5Bcity_id%5D=38#form&page=5

You only have to add the data-id attribute to obtain that part

house.find('a',class_="button-observed observe-link favourites-button observed-text")['data-id']
