Studio Apartment to rent within the landlords home

We live in a new build PASSIVHAUS which is a high spec eco house. The house is 3 years old and has triple glazing and very high insulation. There is a Mechanical Ventilation Heat Recovery (MVHR)system which filters x3 air from outside into the house which is later drawn out through extractors passing through a heat exchange. The temperature of the house is constant day and night. Cool in summer and warm in winter.
We have shared our home with others for many years and made many good friends from around the world. However in this new house we have built in a studio apartment which is self contained but we share the front door and hall stairs and landing. The lodger can use our washing machine by arrangement.
Council Tax is in Band F.
The street is near Beech Road which has many bistros and eateries. We are 5 minutes walk from Chorlton Ees an area that extends for miles along the banks of the river Mersey which is lovely for running walking or cycling in nature.
There are 2 buses that run frequently into the city centre via Manchester Universities and 2 trams that stop at Chorlton offering speedy transport into the city centre and beyond.
