I took pieces of the walks suggested within; specifically the Bloomsbury and Soho and City walks. Was a good resource, not particularly great for a time-pressed visitor, but perhaps for a Londoner.
Highlights from my walks included actually getting to tour 44 Bedford Square (Lady Ottoline’s house where V. Woolf and H. James frequently visited) which is now a VAT tax office. Also Pepys Navy Office site, St. Dunstan’s ruins, the Temple, Virginia Woolf’s various houses about Bloomsbury, Thackaray/James in Kensington.
