Thanks for the positive insights to my suite Richard, that it is bright, has new linens and towels, close to parks, Trout Lake, sorry you didn't find Commercial Drive *nice* it is not as yet gentrified as most areas in Van but unfortunately will get there soon.
As for the negative ones, the list is long but thankfully unique to your stay. I take great pride in ensuring cleanliness and comfort and would have been very amiable to your concerns if you had let me know during your stay. To try and set your mind at ease that you did not stay in a grimy place - I have the stove and fridge pulled out and floors washed behind them every second guest, the carpets are steamed at the end of each season and the swatches of carpet at the couch may be a bit less clean then the spotlessness of the carpet under them (ppl like to snack and watch TV and the swatches are there to protect the full carpet) - oh all the windows are new as of June 10th 2015, so they really have no had much chance to get as dirty as you thought they were. I use the finger across the surface test when in doubt. As for the kitchen being bare bones - there is every thing you need to make lovely meals, new pots and pans as of the spring, coffee maker (with filters) , kettle, toaster, microwave, teapot, basic spices, dish cloths/teatowels, dish soap, dish rack, laundry facilities (soap included), Britta water filter - maybe you missed a dishwasher as there is none...but that is stated in the listing.
Bugs - yes they are seasonally more of a nuisance than at other times, the moths have been more present than usual this year but the hot weather seems to have killed them off for now.
Next time you are this dissatisfied with an Airbnb rental you have booked PLEASE let the host know as they (as I) would be more than happy to address your issues and do our best to rectify them. Ensuring my guests have a great stay in Vancouver is truly top of mind for me.
