I unfortunately have to give my stay only 3 stars due to the unexpected change and ensuing dishonesty displayed by the host. While everything else was as expected and most basics being at or above expectations, this issue occurring the first couple of days of my stay overshadowed the otherwise great Airbnb in terms of cleanliness, size, brightness, furnishings, and location.
An amenity that I had specifically checked to be included became off limits to my use after checking in. I tried a couple of times to politely and indirectly ask and remind the host that the amenity had been included at time of booking, but the host decided to change the listing on me during our discussion and essentially lied about it being included there in the first place. Fortunately, I had recorded the required proof for my case and with Airbnb's help and mediation, the host allowed me use of the amenity (which I found had none of the "difficulties" that the host had mentioned were reasons why I could not use it) and I was satisfactorily compensated for the day I went without. I can definitely commend the host on quickness of issue resolution once she was contacted by Airbnb, although it did take numerous messages between myself and Airbnb to get to point of host/guest resolution.
Overall a good stay, problem aside, but I highly recommend reconfirming with the host the availability of required amenities before booking, and taking snapshots in case the host again has a last minute change of mind. Dishonesty and failure to own up when caught are poor ways to establish a solid and positive line of communication with the guest.
