Upon check-in, they take a photo of your credit card (both front and back), make you write down your credit card number, expiration date, the zip code, and security code in their paperwork. I expressed my concern about doing this, and they said that is mandatory, otherwise you can't stay there. Two days later after checking out, there are over $800 of unauthorized charges. My credit card has been somehow cloned. This was the only place that I used my credit card in the past week. Is it a coincidence? Perhaps, the Capital One Credit Card fraud department will determine this. I don't know for sure if this place is the culprit, but I strongly advise that people stay away from "Stay City Apartments" (the company that runs this operation). I'm surprised that Expedia allows a company on their website that allows a company that operates with such insecure credit card operations.
