Dan and Jess's place is exactly as described and is really warm and homely. The bedroom is very cute. It lacks a desk, but they make sure to give you your own private space at the table in the dining area. They offered to share most of the area and items of the house, and are extremely considerate people.
I started with an intention of staying for just a month, but then continued to stay for 3 months.
One more thing, the Horfield area is a very nice place to stay. It is quiet and residential, but not very far from the city centre and very well connected. Gloucester road is also nearby, with a lot of eateries and pubs on offer.
