Looking For Buddy Ups

I would love to find a roommate situation that feels like home rather than just a flatshare for convenience. Where we look forward to seeing each other, cook for each other, have movie nights, and hang out together on occasion when we're free. I have quite niche interests and hobbies though which means rolling the dice and moving in with strangers usually results in us having nothing in common and being unable to foster anything more than a polite friendship. I know not all of my criteria will be met, but I thought I would lay it all out on the table and hope to find some likeminded people.

There are a few places in London that I love to frequent and it would be amazing to find somewhere that's within walking distance of at least one of them, meaning at maximum about a 30 minute walk away. Said places being: London Bridge/Borough Market, the Southbank, the Tower of London, King's Cross Station, and Trafalgar Square.
