I would think 99% of all hotels and restaurants here would not accept "pets" (I assume you mean a dog not a goldfish?) unless it was a guide dog or hearing dog or such like, more so since supposedly dogs are haram and some Indo's don't like dogs, plus the hygiene issue too.
Best thing to do is email the hotel directly, I doubt very much there is a website unless you do a special search on traveloka etc etc? Under filters.
Is there a reason you want to bring your "pet" with you? Do you plan to leave it in the room or take it out with you? Wouldn't it just be easier to leave the pet with a friendly neighbour or in a kennel or cattery?
Yes I know a pet is part of the family, but hotel room is only one problem - also malls and restaurants would frown on you bringing a pet with you?
Since you didn't specify I assume it is a dog?
