Looking for a friendly place to call home

I'm currently looking for a short-term place to call home in Brighton. I'm a content writer and work mostly at a co-working space near Brighton station . Outside of work I do a lot of yoga, love walks and just getting to explore more of Brighton. I do help look after a friends dog, he's a very affectionate and well behaved whippet named Otis - so it would be nice if he can come around at times but not mandatory.
