I have been at many Airbnb's in many countries and Adrian by far is one of the best hosts I have had. He is quick to respond and always addresses your requests or questions in record time; he is also super friendly, is a kind man and a reasonable person. The basement suite I booked was not huge but had everything you need to stay for a few weeks or a few months, including your own entrance and washer/dryer right outside your room. I once asked for extra pillows and Adrian delivered them in a matter of hours; another time I locked myself out and Adrian was able to come and let me in. He would often check with me if I was okay and if there was anything I needed. The main kitchen upstairs (which I could use if needed, but never had the need) and living room is always kept clean and all paper/bottle/plastic/organics recycling bins are always clean and tidy. There are 3 rooms on the 3rd floor who use the kitchen on the main floor, so you can also get to meet some of the other guests from time to time if you go upstairs to recycle or if you hang out in the living room upstairs.
The Commercial Drive area is also very convenient for catching the sky train downtown (<8 mins) other express buses and for getting around in general; the Street Commercial Drive also has lots of cafe's and restaurants of all kinds from around the world and a large grocery store and many other smaller ones are within walking distance, including a gym at the City of Vancouver Community Centre (6-7 mins walk). All in all, I would recommend Adrian and Mary's Airbnb, and Adrian for being an excellent host!
