Looking for a special room

Hello, I am a girl of 49 years old, vegan, I don't smoke and I don't drink alcohol. I've two friendly cats. I am looking for a room in Porto, near the center of the city, but in a quiet area with a garden for my cats and it could be better if its near to the beach. I usually work at home through internet and I need enough privacy. I am a therapist of natural medicines, ( I am Homeopath and Naturopath  for pepple and for animals, too ) and I am a commercial of natural products for health. i am spanish but I was born in Paris, and actually I am living in Barcelona, in a litle town very close to the sea.Thank you.
