A short walk from Oxford Circus tube station, Kaffeine is easily one of the best coffee houses in London. Whenever I'm working in the area I pop in beforehand to kick start my day with a well-made cappuccino.
The Design Museum is a museum in Kensington, next to Holland Park, which covers product, industrial, graphic, fashion and architectural design. There is also a nice cafe on the 1st floor with beautiful views of the park.
There are libraries full of screaming children and strip lighting, and then there are libraries like The London Library. Whenever I’m there it’s hard to believe I’m not caught inside a wonderful dream, because everything about this place is so perfect as to be almost unreal.
