@Kathy121 said "We had no idea to tap the FOB on the door opener, which caused us huge delays getting in from the garage, arriving tired and late."
Unfortunately, AirBnB is pretty much a self-service type of situation. If you require guidance in using something like a fob, you would probably be much happier staying in a full-service hotel, where there is a customer service staff and usually at least one person at all hours you can call on to provide instructions and help with the facilities.
Another thing to keep in mind is that since AirBnB is again self-service, like staying in a friends condo, and not a hotel. It is very common that guests are provided a clean room with one clean set of towels per person and one clean set of linens per bed and supplies such as toilet paper and soap to last long enough until they get situated and if the guest wants they room cleaned, clean towels during their stay or they need more supplies, it is the guest's responsibility to clean themselves, wash their towels and buy additional supplies. Again it is not a hotel and does not try much hotel level of service. AirBnBs are generally clean and comfortable. but since they are individually owned and people generally have less desire to make them like-new and price themselves out-of-the-market, AirBnBs are remodeled and refreshed on a longer schedule so furniture may be scratched, and bed corners scuffed.
Perhaps one of the reasons AirBnB seems unresponsive to your complaints is that some of the things that you are complaining about, such as not being told how to use a fob or really not deficiencies with the host's property but are actually personal, life-skill challenges and if the host were to enumerate all of the necessary life-skills that are needed to stay independently in an apartment building the host's house manual would be 100 pages long.
All and all, with AirBnB you are sacrificing level-of-service and frills to save money. You got a 2 bedroom condo with a washer and dryer, and parking, pool and gym for $119US per night According to Booking.com a three-star hotel room in Mississauga is $93US. So you are getting a lot more space and amenities through AirBnB, but you are sacrificing personal service and hotel-level upkeep.
Hope it works out for you, but at the same time, I think a lot of the problem was mismatched expectations.
