Dennis was a very welcoming host and very receptive to any questions I had. He always responded very quickly and politely. He let us drop off our luggage early too, which was a big help. Location was pretty convenient and close to waterfront, metro station, and a Safeway, but not really a 15 minute walk to the Aerospace museum as claimed (unless you want to spend an hour walking round-trip - taking the metro is much faster). Overall, I would stay at his place again.
