Considerate Female seeking room in Notting Hill

I am a professional female, a respectful and considerate tenant, looking for a single or double room. I am available to move asap and have a budget of max 900pm. I would prefer to share with females or couples in their 30's who are down to earth, easy-going, who likes to keep common areas nice and clean and their home environment cozy and calm. No smokers, please.
