I am writing to express my disappointment in the recent Airbnb experience I had with this particular host. Unfortunately, upon arrival, I was denied access to the property as the host had failed to inform the concierge of my arrival. Furthermore, upon entering the apartment, I found it to be in an extremely dirty state as the host had failed to arrange for cleaning prior to my arrival. When I brought this to the host's attention, they were unresponsive and displayed a clear lack of empathy towards the situation. Adding to my dissatisfaction, the host requested a deposit of $500 to be sent via e-transfer, which I found to be an unusual and unnecessary request. Based on my experience, I would not recommend this listing or host to any potential guests.
