Have you seen this map (http://i83.photobucket.com/albums/j297/anteka/Sherlock%20BBC/tumblr_lzwki1eexY1qmta8go1_1280.jpg)? It helped me finally figure out the layout. I still have no idea where the hell John sleeps, but, it's still helpful.

Thank you so much for watching and for commenting! I'm so pleased you enjoyed it!
