SO glad I ended up using Luxor! I just wanted to treat someone with a town car to take them to dinner for a significant birthday, and found Luxor online. I made the reservation on their website, and communicated completely via email.
Their customer service is outstanding -- I had to make a few changes to my reservation, and they responded quickly and efficiently, keeping in communication regularly as well. Our driver was early, and I received a text letting me know where he was. He was super nice, and the car was spotless and very comfortable. I also felt that it was a reasonable price, particularly having compared to other companies.
I will definitely use this company again and highly recommend them!
