Pet-friendly house and flatmates wanted!

Hi! My small dog Trilly (7kg) and I are seeking for an accomodation. I will begin my MA in International Journalism at City University on the 18th of September, but I plan to move in at the beginning of the month or at the end of August.
I am tidy, sociable but not too much of a party lover and I would like to live with other students or professionals with whom I can hang out with. I don't smoke but don't mind if you do, I am a nice cooker and a very relaxed person. Guests are okay for me and in fact I myself plan to have friends visiting me every now and then.
Trilly is a very smart dog, she likes playing with her toys but also cuddling (a lot!) and she is really good company. She is usually very sociable with people, so if you are considering taking a pet on your own but you don't have enough time... well, we can share :)
My boyfriend is joining me in London sometime in January or February, so I am looking either for a maximum 6 months contract or a place where couples are okay.
I am very flexible as far as city zones or house features are concerned, so contact me if you think you could be interested!
