Although my skating days are now over, Stockwell Skatepark located just behind Brixton Academy is one of the reasons I moved to Brixton. It’s an excellent place, lumpy and hectic but totally friendly with decent Portuguese coffee and cakes just next door.
Arguably the best café in London – or at least East London – with an incredibly welcoming atmosphere, delicious array of food and drinks, and hypnotising views to Broadway Market. Visit early in the mornings, for a roque-monsieur at lunch, or to get lost in their cheese selection at the market stalls on Saturday. Warning: addiction likely to occur.
Slightly biased as this is where I live, but Stoke Newington is great place to spend lazy saturday / sunday afternoons getting sloshed with friends. There are 10 + pubs within walking distance who all are great places for one reason or another. I'll pick out the White Hart for its huge beer garden...
London’s wildest and best park to get lost in. Just follow your instinct, chase trees, go up to the viewing points and you’ll always find breathing and mindspace in Hampstead Heath. If you can, visit often, as it goes through wonderful changes over the seasons.
