wanted pet friendly room to rent short term

Hi, I'm moving to Madrid next month due to work and looking for a room to rent  for me and my well behaved pooch from 22nd of November until 23rd of December or possibly after 'los reyes'. It is only needed short term as I will be flat sharing with another teacher who is moving to Madrid after Christmas.  I'm happy to pay a deposit if you have any concerns about renting/sharing short term to someone with a dog. Many thanks Nikki
