It was a fantastic stay in London, above all due to the nice apartment and friendly welcome with a first supply of coffee and water already there. As others already wrote, we'll be back and the only thing we need to make sure is to find a slot in which we can go back into this place - no need to look for anything else.
Within 15 minutes walk you can easily reach Central London places such as Leicester Square or Soho, or else Tower Bridge to the East. Of course, the Southbank itself has plenty to offer too.
To make things short: we highly recommend to stay in Anne's place when planning to go to London and look forward to coming back soon...
