David was really helpful in letting me know how to get in and he was there when I arrived as well! I didn't have many questions for him since I'm used to living in London. He offers guests a nice guide that he's made himself - while I didn't need it, it would be useful to other people. I did not see him much throughout my trip due to our schedules but I had a nice conversation with him on my last night. My only caveat to future guests is to make sure you know the distance to transport access, whether it is the Tube (Bakerloo or Overground) or the airports. David's apartment is not immediately nearby stations, which I did not mind at all, but others may be expecting something closer.
