The Union Jack Club. I have just spent a few days in London staying at The Union Jack Club. This is a great facility in the middle of London and not at all expensive. It is ideally located for most sporting events. Close to Wembley, Twickenham Lords , O2 arena and the Oval. If you are intending to book during any particular sporting event it makes sense to book in advance.  contact them on or phone 020 7902 6000.
