London in September / secluded naturist space

Hi there - I am looking for a secluded garden or a room/space in someone's flat where I can be naked, meet a friend, and be relaxed. My accom in London is a shared non naturist flat and so I'm looking around for possible daytime hosts. I'm down 10th Sept for a few days incl weekend. Love to chat with someone.
