Clean and professionally run but not ideal for business travelers (explained in cons below). Airbnb does not allow half stars, I would say 3.7 stars, definite not a full 4 but not so bad to be a solid 3.
I have stayed in many airbnbs and travel for both pleasure and business. You can read reviews for me as a guest to see that I have a good history as a guest. I am leaving this review as it would be the kind of review I would find helpful as a guest and do not have any bad feelings towards the host.

Pros:
Apartment was very clean as other comments suggest. Downtown Vancouver is generally very walkable, so the location falls under same expectations, not any worse or better than other locations I have stayed in various parts of downtown Vancouver (it is a couple of blocks from a sketchier area, but I was fine walking around as a solo female). Hosts had good instructions for getting in the building . Communication was solid and they were understanding of my having a delayed flight that made me arrive at the apartment just at 10pm, which was the latest they would accommodate checkins without charging an extra $40 fee. The checkin process was automated so it did not involve meeting the host.
Cons:
My main issue with the stay as a business traveler, which I stated I was in the booking request are twofold. Firstly, despite paying $90 cleaning fee, there was an excessive amount of expectations for what to clean upon the mandatory 11am checkout: I will copy and paste below the instructions I got from the hosts so other people staying will know. As a result, I followed most of the instructions, but did not take out the garbage to the special floor or start the dishwasher (though I did load it all). I also left the windows open since they were open when I started the stay--it was a hot couple of days in Vancouver. I thought charging $90 for a cleaning fee and asking for all of the following to be done was very burdensome. The hosts were also unable to accommodate asking a place to hold my luggage for a few extra hours after my checkout because I had a late flight. Again, I know they are not obliged to do this, but compounded with cleaning instructions, it added to the inconvenience of having to check out at 11am. Keep in mind that if you are traveling in the summer, there is no AC (host does list this in description) so it will be very hot. Even with fans running.
Checkout cleaning instructions:
“Before you leave, we just ask a few favours to help our housekeeper prepare for our next guests:
Please load all dishes into the dishwasher and run it on the normal cycle.
Please strip the beds (sheets, duvet covers and pillowcases) and leave all used laundry, towels, bath mat and T towels on the floor by the washing machine.
Please empty the cupboards, fridge and freezer of your food.
Please turn the heat off (if not already).
Please leave the suite tidy.
Please turn off the TV.
Please close all windows.
If the apartment requires additional cleaning above the allotted times for your suite, your damage deposit will be utilized. Standard check times allotted for check out cleans are 3 hours and seldom is this ever necessary.
Garbage: Take the elevator down to the lobby level (G). Turn left when you get out of the elevator and go through the door and down the corridor (you will need a FOB to enter).”
