Empty double room to rent in two bed house

Hi I'm Mel I'm 25, looking to rent out a room from my house that I am renting. £100 a week all in. The room will be empty with space for a double bed and wardrobe etc. I'm a smoker but I smoke outside. I have a collie x spaniel who is nuts she's outside when I'm out and sleeps in my room of a night she is house trained. I like chilling out through the week after work I tend to work 12 hour shifts. The odd friend will pop in for a few hours and of a weekend I may go out have a few girls round for drinks then go to Liverpool. But I don't have lots of noise or party's in the house. I will consider a male or female in their 20s-30s any more info wanted message me :) train station and bus stops 5 min walk away
