Hi Amandine,
We posted some guidance on how to find pet-friendly properties on OpenRent here:
Beyond that I can see there are some aspects of your search that are different - for example the fact that you’re currently overseas.
I would advise that when you contact landlords through OpenRent you simply make them aware of your situation, and they may be able to arrange a viewing via video call initially. We do strongly advise though that you view the property in person before agreeing to rent it.
Perhaps some other tenants will share their experience of this also.
Best of luck with the search!
Simon
