I've stayed with Gill a couple of times now and she is a wonderful host and will make you feel completely at home.
Everything is perfect with the room and the house itself has a nice 'feel' about it so, it's a nice place to be able to relax and feel comfortable.
10 min walk to Brockley station for link to London Bridge, Canary Wharf but Nunhead is only a couple of minutes away which has a direct link to town (Victoria coach station)
