33 years old, with a Jack Russell Terrier Pino from Latvia, looking for accommodation in Siena

I am looking into any kind of accommodation as my only request is the place is dog-friendly. 
My small and well-behaved Jack Russell with be with me. I know this may be a harder aspect in order to find a place to stay, but I have lived and studied in Florence before and somehow I managed to find a dog-friendly place. I hope Siena is welcoming us as well. 

About me - I am doing my masters in program called Creative Industries and Growth Management, will be relocating to Siena as I really want to perfect my Italian, as my future plans involve to moving to Italy anyways. 
I have studied interior design prior, at the moment building my own business. I am creative, with positive mindset and definetly minding my own business :) 

I love to create the space and vibe around me peacful and beautiful, I find interesting to experiment in the kitchen with new flavours and make some dinners to have a great time together. 

I am an easy person to live with, I enjoy company and things to do together, but I respect my own and others private space and time. 

Hope to find a friend and a place to call home during my time in Siena. I am super excited to move there for this experience, so can't wait to explore all the beauty of Siena! :) 

My dog Pino is super friendly and he will not be a trouble :)
