Room Available for Professional Dunmurry

i am a divorced father of 3. my kids are all grown and live independently elsewhere. I have been a landlord for many years since the kids went to uni. At this time there is one long term lodger in the house for the last few years (a female nurse) and I do some Airbnb...but I am moving to long term lets. I am ideally looking for quiet self contained professional. The house is in a quite area beside Derriaghy train station so is very convenient for road rail and bus links to Belfast and Lisburn. I smoke and dont mind if residents smoke but only in kitchen. Maddy the cat is the other resident. She loves people and is the Boss of the House!
