Nice to see someone who's honest about their dog @Sonam37 !
People who ask me about bringing pets always swear that their dogs are better behaved than any human on the planet ...😀
Do you have to be in central Cape Town? If not, it may be useful to look for Airbnbs on farms, smallholdings or wine estates - if your search area is wide enough, there are definitely options that should be suitable (and highly enjoyable for the dog). You could perhaps put your requirements into a chatbot and ask it to suggest some listings that could work.
