Double room for part week rental: 2-4 nights/week

I’m looking to let my spare room to a friendly, quiet, clean, non smoking person for 2-4 nights a week.
The room has a double bed and black out curtains, a locker and a bureau.
Not tons of storage space, so would suit part week renter.
Share of bathroom.

Sorry, NO RENTALS FOR WHOLE WEEK.

2 nights per week = £400/month
3 nights per week = £500/month
4 nights per week = £600/month

My flat is newly renovated, ground floor with garden front and back. Parking possible with permit.
My 8 year old Yorkipoo lives here, too, so you’ll need to like dogs.
