Room in a shared flat

My son is a student in another country and I am subletting his room to a student or a young professional. Sharing the apartment with me and my daughter, also a student in the university. The room has a large corner mirror wardrobe a queen size bed and a night stand. The tenant can have a shared use the living room, dining room, kitchen, bathroom and the terrace. No boyfirends or girfriends can live. This is a studying and hard working non-smoking and non-drinking people's non-party home.
