Jack London Queries: Did Jack London ever stay at the Castle by the Sea in Sausalito while he was writing The Sea Wolf?

I have a question. I used to work for the Jack London Historic Ranch and Greg Hayes was my former boss. A wonderful man. I was saddened to hear that he passed away or I would have contacted him. My question is: Did Jack London every stay at the Castle by the Sea in Sausalito while he was writing The Sea Wolf? I am currently a park ranger for the US Army Corps of Engineers at the Bay Model in Sausalito and I am asking on behalf of the Sausalito Historical Society. The building is still here at 221 Bridgeway and I think they would like to commemorate the spot if they knew for sure that JL actually stayed there, even if it was only briefly. Do you have any evidence to support the legend? Please let me know. Thank you. Linda
