Lodger required for huge double attic room/studio

We are a family of 3 (Mum, Dad & a 12 y. o. Boy) in a nice centrally heated house in Swindon, ideal for walking to work in town centre and near to the Outlet Centre. We have a huge attic room which is really a studio flat as it is ensuite, available immediately either furnished as it is at present with a new double bed, bookcase, big comfy chair and bistro table and chairs, or unfurnished if you'd prefer your own furniture. It's newly carpeted and there's plenty of storage. The photo doesn't do it justice! The roof windows tilt and open and are fitted with blinds.
We have a lovely lounge and diner which you're welcome to share, and also a newly fitted kitchen with all mod cons, or have a microwave in your room if preferred. We have full fibre broadband, Netflix and other media.
Outside we have a gorgeous little garden and seating under a cuppola and decking.
There is a dedicated parking space for you too.
No other bills to pay, just the rent. This covers heating, cooking, showers, wi-fi, Council Tax, everything.
As we both work we're looking for a clean tidy reliable person who will pay the rent on time.
Sorry, strictly no smokers, though you can vape in the garden.
Viewing any time from 18th August.
