Hosts never responded, stayed elsewhere

We wanted to book a room, the room had good reviews. Put the card in and nothing. We gather that hosts don’t have to bother to reply if they don’t want to book you in. Personality, just a reply saying they are unable to do so, for whatever reason, is fine, but not nothing. We were not really sure they even got our message. We ended up going elsewhere. And you couldn’t write a review of this as there was no place to put it as we hadn’t actually stayed. For a first time user, this left a bad taste.
