A large group of friends and I visited Vancouver over 4 days, and we really enjoyed our stay at John and Deb's place. The neighborhood is really pleasant, and there is a great park and commercial corridor all within a 10-15 minute walk from the house.
The backyard and deck was definitely a major highlight of the house. Beautiful garden in the back with tomatoes, grapes, plums, etc. We grilled up some food and chilled on the deck more than once, as it was the perfect set up for hanging out with old friends.
Overall, I would definitely recommend a large group stay at John and Deb's (a total of 4 beds plus sofa space). It was a great way to experience Vancouver. John was so quick to respond to my messages leading up to and during the trip. It's clear that John and Deb just want their guests to enjoy their home and Vancouver.
