Large garden studio, bills incl., central location

We are Fidel and Oliver - gay, vegan, married professionals, living in LeightonBuzzard, work in London. We are within easy walking distance to the high street and train station. We live in a 4-bed end-terraced house with 1 cat, 2 Jack Russells. Hence, you must get on with animals, pet hair and smell. The house has benefited from having new flooring and an open plan kitchen/dining area. We are offering the garden studio room which is unfurnished but could comfortably fit a double bed, bedside units, sofa, a wardrobe and a wall mounted TV. It also has private access to the garden, an office shed and its own entrance. We are looking for someone who is tidy, and looks after the room. We would expect reasonable contribution in cleaning the house.
