Unfortunately not. The Plum Guide only lists entire properties.
We classify an entire property as a rental property (studio, apartment, maisonette, house, boat, castle, treehouse, igloo etc.) that your guests have entirely to themselves for the duration of their booking. They are not permitted to share their property with anyone who is not a member of their party.
We do not list private rooms, spare bedrooms or cupboards under the stairs. Even if they are beautiful cupboards under the stairs.
