I travel a lot using Airbnb, and this was by far my best experience, even compared to stays with other superhosts. William's place is SPARKLING clean, and there are a lot of other thoughtful touches that made the stay great.
William himself is extremely friendly and accommodating, and always had a fun story to share whenever I ran into him in the kitchen. I actually accidentally took something from the room as I left and only realized once I was at the airport. I let William know about it, and even though it was a valuable object, he wasn't upset at all and just told me to mail it back to him at my earliest convenience. William's wife was great as well. I was late for an important meeting and didn't realize that Uber wasn't available yet in Vancouver. She called a taxi for me using her app, which saved me a lot of time that I would have wasted trying to figure everything out.
Overall, I think the room is a steal for anyone looking for a few nights' enjoyable stay in Vancouver. I will absolutely be returning to William's place the next time I'm in BC.
