Great space. It's a second-story bedroom in a historic but well-kept (nicely renovated) home. The room is basic and plainly decorated but sparkling clean. The bed is comfortable, and a small work desk is provided. There were plenty of outlets to charge a number of devices. Wifi was fast and reliable. No AC (but AC is rare in Vancouver) but the window opens to cool night air and there's a fan (with built-in heater if necessary).
The bathroom is not attached to the bedroom but is, as far as I could tell, for the sole use of the Airbnb guest. (The other bedroom upstairs did not seem to be actively occupied.) It's a basic but perfectly fine bathroom and was kept very clean. Shampoo, etc. plus a towel was provided.
The location was absolutely fantastic for my needs. It's on a quiet street just a couple of blocks off of the main drag between Richmond and downtown Vancouver. I ended up having a rental car, and it was barely a 10-minute drive to the airport in the morning with several convenient gas stations en route. Had I decided to rely on public transit, Google Maps indicated it would have been about 25 minutes, which is pretty fantastic (the house is about a 15-minute walk from the Marine Drive SkyTrain station, which then connects directly to the airport; for those who prefer to walk less, you can walk about half as far and connect by bus to the SkyTrain).
I took advantage of the proximity to Richmond (also a 10-minute drive or accessible by SkyTrain) to try a meal at one of Richmond's many super-authentic Chinese restaurants. I didn't get a chance to stop by, but the Richmond Night Market is another option on some days of the week.
All in all a fantastic stay, especially if you value proximity to the airport. Would definitely stay again if I'm back in the area!
