If we're talking central London, I'm partial to Bloomsbury. It's very centrally located and is, generally speaking, a relatively quiet area. The British Museum is nearby, as is the Russell Square tube stop. I have no idea what rentals are available though. I have no idea what cycling in the area would be like. I'm not sure how inclined I'd be to ride on the streets in Central London. I think taking a day trip to, say, Oxford for a bike ride would be more fun.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
