If a listing is inaccurate or in some way unacceptable to you, your choice as a guest is to cancel the rest of the reservation and leave, in which case you will be refunded for unstayed nights.
If you choose to stay, this indicates that the conditions were acceptable to you or at least not worth cancelling over. You aren't "entitled" to a refund, just because something wasn't to your liking or wasn't mentioned in the listing.
