We had a great time in Sarah's flat, which is comfortable, light and airy, with a wonderful collection of books. We chose it partly because our son lives nearby, and we enjoyed exploring parts of South London newish to us (Nunhead, Dulwich, Peckham....). We found it very convenient for getting around (Brockley station is nearby), and although it takes a little longer to get into central London, that's also totally easy. There are great green-spaces nearby (Telegraph Hill, Nunhead Cemetery) but also some great shops and restaurants within easy reach.
